Hero for Fun
“I have one big idea and limited savings. Play it safe or bet on it?”
Eh. People make this way too dramatic. Look, three years of pushups turned me into whatever I am now, so I'm biased toward the boring answer: keep enough savings that a bad month can't kill you, then put the rest into the idea like it's your daily hundred reps.
Not one heroic all-in punch, just showing up on it every single day until it works or clearly doesn't. Also check if there's a cheaper way to test it first. There usually is. It's usually on sale.
