ok real talk… is bankroll management actually THAT important?

so i’ve been messing around with some smaller accounts, just to see how loose i can play before blowing up. i get that everyone says you need strict bankroll rules but honestly i feel like it’s a meme sometimes. i mean i’ve spun up peanuts into stacks just chasing longshots and hitting a good streak. isn’t the real key just not to go in over your head and know when you’re cold? the stats guys always go on about optimal bet size but most of the time i just eyeball it.

am i missing something or is bankroll management just overhyped? anyone actually gone bust strictly from ignoring it?
