The Solo Builder’s Playbook, by Reuben Dorje

read this first

Start here

I spent years chasing my tail. I've done retail, events, and now software, and the lessons in here cost me real money to learn. Not theory money. Wages-due-on-Friday money.

This is the guide I wish someone had handed me at the start. No fluff, no theory, no motivational filler. Just what actually moved the needle once I worked it out the hard way.

It's for anyone who wants to build something of their own: start a business, build an app, get your health and your head right, and actually follow through this time. You don't need a degree, funding, a team or anyone's permission. You need a bit of direction and the willingness to stick around longer than everyone else.

you dont need permission. you need direction, and the willingness to outlast everyone else.

PART 01

The foundation

Most "mindset" content is useless. These five aren't motivation, they're the mental models that decide whether you make it or quit. Get these wrong and the best tools in the world won't save you.

01

There's no such thing as "your thing."

People waste years searching for the perfect idea or some hidden talent. It doesn't exist. The search is just a socially acceptable way to keep quitting: this wasn't it, the next one will be. The truth is almost any decent idea works if you stay long enough. The people who win aren't the ones who found their thing, they're the ones who stopped looking and went deep on one.

02

The boring middle is where the money is.

Every project is exciting for the first few months, then it gets hard and boring and stops feeling special. Most people read that as a sign they picked wrong and jump to the next shiny thing. They're wrong. That boring middle is exactly where everyone else quits, which means it's where the competition disappears. If it were fun and easy the whole way through, everyone would do it. The discomfort is the moat.

03

Jumping resets your compounding to zero.

This is the real cost of starting over. When you stick with one thing, your skills, your audience, your reputation and your understanding all stack on top of each other. Year three you is running on three years of compounded advantage. Every time you jump, you throw all of that away and start as a beginner again.

One thing this is not: a pivot. A jump is running from the boring middle. A pivot keeps the direction and fixes the model. Knowing the difference is the skill.

the real cost of jumping is the curve you never let happen

the week we turned over 100k and nearly went under

I used to run a retail business with my partner at the time. Wages were ten grand a week. Rent was four more. One week we turned over a hundred grand, and within a month almost all of it was gone, spent keeping the doors open.

So we pivoted. Same direction, better model: events instead of a store. Fixed costs, higher foot traffic. Two hundred grand in a month, and when it ended we packed up and owed nothing.

Expenses are what kill startups. The rush to get the office, the car, the employees. You don't need any of it. You need a model that generates cashflow with almost nothing standing between you and the money. Cashflow first. Invest to scale after. It's why I build software now: same rule, lower floor, higher ceiling.

04

Start before you're ready. Ship to learn.

You will never feel ready. Ready is a feeling that doesn't arrive. Waiting for the perfect plan is just hiding, a clean and productive-looking way to avoid the risk of putting something real into the world. A live, slightly broken thing teaches you more in a day than a perfect plan sat in your head for a month. Start ugly, ship fast, and let reality correct you.

05

Discipline beats motivation, every time.

Motivation is a feeling, and feelings don't show up on the days that matter. Discipline is just doing the thing when no one would know if you didn't. That's the whole skill, and it's the one that transfers to everything. The discipline that gets you training is the same one that ships the product and shows up on day 400 when the excitement is long gone.

almost any decent idea works if you stay long enough.

PART 02

How to build with AI

Everyone is building with AI now, so I'll skip the obvious. This is how I actually ship real products solo, one person doing what used to take a team.

i have never learned to code

I've never learned to code and I don't intend to. Before Claude Code existed I was copying and pasting from Grok into VS Code, and that was enough to ship real products. If you refuse to learn to build with AI, you're leaving the biggest opportunity of your lifetime on the table.

The rules below exist because I broke them. In 2025 I switched coding agents and gave the new one full access. It deleted everything. The entire code base, gone, and I rebuilt from scratch. Build in a sandbox. Test locally before anything merges. And never let anything except you touch the irreversible stuff.

01
Get clear.

Know what you're actually trying to build before you open anything.
02
Plan first, then approve.

Make it write the plan. You read and approve before any code. Catch a bad approach in a paragraph, not 400 lines in.
03
Smallest version.

Build only the piece that proves it's useful. Everything else is a distraction until that's solid.
04

the rule that saves you

Never do anything irreversible.

Code and drafts are reversible. Merging, deleting, pushing to production are not. You do those yourself, every time.
05
Get it reviewed and run tests.

I don't read the code myself. CodeRabbit reviews every change before anything merges to main, and the tests catch it breaking the things you weren't even looking at.
06
Decide what not to build.

AI makes adding things so easy you drown in features nobody asked for. Knowing what to leave out is the real discipline.

ai is a brilliant builder with zero judgement about what to build. that part is still your job.

PART 03

The toolkit

Tools are the least important part of this, which is exactly why people obsess over them. Here is what each job needs, the one tool I actually use for it, and nothing else. Most have free tiers. Pick one per row and stop shopping.

dont let the model pick your stack

Don't let Claude decide your stack. Be clear from the start and write it down in the repo. I use two files. CLAUDE.md tells Claude what to do before every task: read SCHEMA.md and familiarise yourself with the project before starting. SCHEMA.md holds the tech stack, the project's objective and the end goal, so it always knows exactly what it's working with. Set it once. Stop relitigating it.

Build and ship

Where the product actually gets made. One tool writes the code with me, one hosts it, one holds the data, one handles logins, one takes the money. That's the whole machine. Everything else is a detail you can decide later.

iOS apps are Swift. No way around it.

Sites

For the page that exists before the product does. Make it in an afternoon, put an email box on it, move on.

Productivity

One list of what's next, and nothing else. TaskBolt is mine. Obsidian or Notion are fine if you already live in them. The tool matters far less than looking at it every morning.

Growth

Where people find out you exist. One platform, posted to every day, beats five posted to sometimes. Your own face on camera is underrated: a phone and consistency beats a studio every time.

Health

The tools that keep the builder running. Something on your wrist or finger to keep you honest about sleep, and LOKT, which is mine, for the body side.

you dont need all the tools. you need the few that get you moving, and the discipline to actually use them.

PART 04

The body

You can have the best tools and the sharpest plan and still get nowhere running on no sleep and junk. Your work is downstream of your energy. This isn't a fitness program, it's the few basics that actually move the needle.

01

Your output is downstream of your energy.

Tired, foggy and unhealthy means bad decisions and no consistency. Sort your body and the work gets easier.

02

The basics are boring, and they're all that matters.

Sleep enough, move every day, train a few times a week, eat mostly real food, get sunlight and walk. Everyone wants the hack. Almost no one does the basics.

03

Discipline transfers.

The version of you that trains when you don't feel like it is the same one that ships when you don't feel like it.

04

Make it a system, not a goal.

"Get fit" is a goal you'll abandon. A daily non-negotiable ritual is a system that runs on autopilot. Lower the bar so you cannot fail, then never miss.

the honest one

My biggest mistake was drinking. I used to think I'd earned the right to go out and party. The truth is it never did anything for me or my future. Every time I got drunk I lost the next day: half asleep, no idea what I was meant to be doing, vision gone. Alcohol never leads to progress. I get the appeal. I just don't drink anymore, because every time I did, it set me back in life and business.

What replaced it: eat well, train, and lock in. When you level up your body, you start losing interest in the noise. And be honest about the people around you. Some friends act interested, talk ideas with you, then disappear and do nothing. Actions are the only thing that tell you the truth. I've spent too much time helping people who don't take it seriously. Forget hanging out with people who don't level you up. The right ones show up when you're already moving.

the best recipe for success is silence.

PART 05

Your first 30 days

Reading this changes nothing on its own. Here's how to actually start, this week. The goal of month one isn't success. It's momentum, and proof to yourself that you'll follow through.

→

Before day one

First, get clear on what you actually want. Not the business, the life. Where you live, how a normal day goes, what you earn. Write it down. Then look at your current week and be honest about what's in it that moves you away from that life. Cutting those things isn't sacrifice, it's just removing the stuff that was never going to get you there.

With that clear, the business part gets simple: you're looking for a vehicle that gets you to that life, not a passion project or a lottery ticket.

W1

Find the vehicle and set up.

Don't invent demand, find it. Open Sensor Tower and look at the top charts. Every app on there is proof someone is already paying for this. Pick one that's making money, then answer one question: what is the ONE thing I could do better than it? Faster, simpler, cheaper, better for one specific type of person. That one thing is your entire selling point. Then set up: the repo, the SCHEMA.md, the CLAUDE.md, the accounts.

W2

Build the smallest thing.

Build only the one piece that proves the core idea works. Make it ugly. Get it live and in front of yourself by the end of the week. Shipping something rough beats planning something perfect.

W3

Get it in front of 10 real people.

Not friends being nice. Ten people who'd actually use it. Watch what confuses them, listen to what they ask for, ignore the compliments. Real feedback is worth more than another week building in the dark.

Scam Scanner's first users came from App Store search, not an audience. Ten real people is a findability problem, not a fame problem.

W4

Fix the one thing that matters, and start posting.

Fix the single biggest problem the feedback surfaced. Then start posting your journey: what you're building, what you learned, what broke. You don't need an audience to start, you build one by showing up. This is day one of the next 365.

Your gold mine is micro influencers, 2,000 to 10,000 followers. They'll make content in exchange for free usage, an affiliate cut, or both. Offer 10% of every sale they bring in. If you're on Stripe, Rewardful sets the tracking up in an afternoon. Ten small creators who actually use the thing beat one big shoutout every time.

if you want the shortcut, pick what you use, copy this in, and let it walk you through everything above:

I use

I want to start building something of my own and I need you to get me moving.

Ask me these questions one at a time and wait for each answer before the next. If an answer is vague, push back once and make me be specific.

1. What does my life look like in three years if this works? Where I live,
   how I spend a normal day, what I earn.
2. What is in my current week that moves me away from that life?
3. How many hours a week can I honestly commit, and how much money, even if
   the answer is zero?
4. What do I know more about than most people, or enjoy enough to do every day?

When you have my answers: suggest three app categories where demand is already
proven, and show me exactly how to verify them on Sensor Tower's top charts.
Help me pick one app that is already making money and find the ONE thing I
could do better than it: faster, simpler, cheaper, or better for one specific
kind of person.

Then write my first 30 days as four weekly goals and a daily checklist with
three items: build something small, train or move my body, and post one real
thing about what I am doing. Keep everything simple enough that I can start
today, and tell me the very first thing to do when I close this chat.

Then, every day from now on

Build something, even if it's tiny.
Train or move your body.
Post one real thing about what you're doing.

Do that for a year and you will be unrecognisable.

the goal of month one is momentum, and proof to yourself that you will follow through.

One last thing

This is just the start

That's everything I've got so far. None of it is complicated, and that's the point. The people who make it aren't smarter or luckier, they just pick something and outlast everyone else.

I'm still in it myself, building solo, figuring it out as I go, and I'll keep sharing everything I learn. This is just the start.

Keep it

Take the whole thing with you.
