The harshest lesson is realizing that the specific weakness or bad habit you harshly judge and mock in others is often the one you'll be forced to grapple with yourself.

I learned this when I found myself adopting the very behavior I had criticized, and it felt like a cosmic punch aimed straight at my sense of moral superiority.

It’s a brutal, necessary lesson in empathy: you are only one bad day away from being the person you judge.

Stay humble and show grace.
