Buddha

A prince who had everything - palaces, servants, a beautiful wife - but walked away from it all to sit under a tree and figure out why life sucks. After nearly starving himself to death as an ascetic (spoiler: that didn't work), Buddha realized the answer was neither luxury nor self-torture, but a middle path. His big breakthrough? Suffering comes from wanting things to be different than they are. Stop clinging, stop craving, stop expecting permanence in an impermanent world. He spent 45 years teaching this, walking thousands of miles barefoot, creating one of the world's major religions by basically saying 'chill out and be present.' When he died at 80 from food poisoning, his last words were essentially 'keep practicing, don't be lazy.' Teacher to the very end.
