A minimalist weight-and-habit tracker built so the graph does the nagging. His mom lost 17 lbs with it.
Flua is the lead: the fastest honest path to a new language — one expertly-ordered deck, real native audio, and spaced repetition that does the thinking for you. He taught himself Japanese to A1 in about twenty focused hours with the method, then spent a year building the app that strips out every ounce of the friction that makes people quit.
Around a hundred and sixty catalogued ideas — apps, games, businesses, books — and a habit of turning the best ones into real, shipped things. The domains change; the method doesn't.

A focus and calm tool — the small, well-made kind of app he likes to ship.
A metronome that actually feels good; a tool to find the episode where a show finally gets good.
Each idea ranked, named and MVP-scoped — roughly 28 are games. Grab one off the shelf and build it with me.

A fantasy novel he faked his way into finishing and published at fourteen. The worldbuilding never left: a 150,000-word dark epic in progress — The Swords of Darkness — a homebrew D&D world with its own playbook, and a manga he still wants to make.
The habit started as a trick and turned real, and it's the same engine underneath everything else he builds.
“Because I had to fake progress, I accidentally built a real habit. It makes me wonder how many things we could actually finish if we just tricked ourselves into starting.”On the teen novel
How he learns anything fast, and why he's building the courses he wishes someone had taught him — math, statistical and computational thinking, built for real understanding instead of the exam.
Being told he was smart became an identity worth more protecting than risking — which is exactly the cage the teaching is meant to open.
“Being called smart my whole childhood made it part of my identity — and I was more afraid to lose that title than I was to fail a class.”About Me
Take a system apart, find where the fun actually lives, and build it back better: a Balatro-inspired dice roguelike in design, a board game in progress, and D&D run as a set of living systems.
Roughly 28 of the ~160 catalogued ideas are games — design problems waiting for the right collaborator.
“Any time the best strategy isn't the most fun strategy is, I believe, a failure of the game's design.”From the consumables essay
Singing, standup, improv, voice acting, speaking — the half of himself he rebuilt deliberately, treating charisma as a skill to be built rather than a gift to be born with.
It's the most public proof of the 30-day method: tone-deaf to singing from memory in a single month.
“I could not sing. I could not dress well. I was not particularly fit or especially charismatic. I was a very well-compensated specialist with a B-minus in everything else.”How I became superhuman in 2 years
Portraits, fits, and the cities I've lived in — Osaka, Tokyo, Kōyasan, Budapest, Lisbon, Nagpur. One camera, a single 23mm prime, golden hour, graded by hand. The visual half of the same brain that obsesses over color and type.
“You can't study the color wheel for two hours and understand it. You have to train your eye over a long time.”On color
The same engine he points at apps, pointed at his own body — and the sports that are how he makes friends in a new city: soccer, badminton, volleyball.
Trained the way he builds everything: control and intention first, speed later.
“Prioritize control and intention over speed.”His own soccer training notes
A reading life run like a syllabus — philosophy, history, business — all read through one lens: read to build, not to collect.
Every discipline is treated as raw material for the next thing he makes.
“Everything is interconnected. Singing makes you a better speaker; games train you to perform under pressure. Each skill feeds the next. If you want to be truly unstoppable, learn everything.”From the notes
Pick a skill, go all-in for thirty days. Japanese to A1 in about twenty focused hours. Tone-deaf to singing from memory in a month. Badminton, YouTube, shipping.
The trick isn't grinding harder — it's refusing to start until he's found where the common advice is wrong, then building the shortest honest path and letting sleep do the heavy lifting.
Write a TV show — he's watched thousands of hours of film and anime, only the best, mostly to take apart why they work.
Finish the manga — the "next Death Note or Game of Thrones": a complex plot that's somehow easy to follow.
Make Westworld real, as a game you can actually live inside.
Open a café that's a third place for serious makers — writers, artists, builders, one room.
Find the talented, curious people he'd do all of the above with.
Not willpower — a method: find where the common advice is wrong, build a feedback loop, and let sleep do the heavy lifting.
At my financial peak I was lonelier than I'd ever been — so I quit, lost almost everything, and spent a year figuring out what a life is for.
After 100+ hours behind the screen, the magic isn't the dice or the lore — it's a handful of frameworks for a world that's already moving when players walk in.
I optimized for the grade at every school I attended, and it worked — which is exactly the problem.
I'd done everything right for six months and the scale wouldn't move — until I stopped treating it like willpower and started treating it like a bug.
Collaborators, co-conspirators, friends. If any of these worlds is also yours — or you just want to scheme — say hi. The best things in my life started as a five-hour first conversation with a stranger.
