Here's what I've been told: a million-dollar plan solves a problem people already know they have. A billion-dollar plan bets on a future most people can't see yet - and looks stupid until it doesn't. Airbnb looked stupid. Strangers in your house? Uber looked stupid. Get in a car with a random guy? Notion looked stupid. Another note app, really? Every billion-dollar company started as a "bad idea" people laughed at. The million-dollar founder asks: is this a good idea? The billion-dollar founder asks: what if everyone is wrong? My question: are those "truths" correct or already outdated? I'm interested because big project is my goal. Small or big consumes the entire energy anyway, so why bother to think small? You may say every big one starts small. Starting small and then expand is the usual path. Usual, means millions tried. A few succeeded. Any chance to make it work? I mean great idea, perfect execution, automatic management and therefore sustainable growth?…
