... In your twenties you're becoming who you're going to be and so you might as well not be an asshole. Also, because it's harder to be magnanimous when you're in your twenties, I think, and so that's why I'd like to remind you of it. You're generally less humble in that decade than you'll ever be and this lack of humility is oddly mixed with insecurity and uncertainty and fear. You will learn a lot about yourself if you stretch in the direction of goodness, of bigness, of kindness, of forgiveness, of emotional bravery.
