Criterion
When you die, you’re not judged for the sins you committed, but for what you didn’t try, yet could have. Like if you nearly signed up for a karaoke slot, then got cold feet. Or told yourself you'd hike Mount Kilimanjaro, but kept making excuses about how it would've been a waste of money, and you probably would've gotten altitude sickness anyway. Or presumed you wouldn't be good enough at [the cello, that managerial position, brewing beer, kissing, snowboarding, calling your friend and apologizing], and thus gave up before you even started. That's the only criterion you'll be judged on.
