In your twenties you learn that you never really become an adult, just that people start expecting you to act like one. So you start pretending to be grown up, even though you still feel like a scared little child.
And if you’re smart, no matter how good you get at playing the adult, you won't forget that underneath it all, at any age, you are always a scared little child, with no real idea of what you are doing. That way, you will forgive yourself easier when you screw up, become afraid, act weak, and hide from truth. For these things will also always be with you.
And that self-knowledge will remind you that everybody else are scared little children too, and that will make it easier to forgive them when they screw up. And you will not believe other people who want to pretend that they have it all and know it all, and you will not be surprised when they too fall on their ass.
And you will naturally show love and compassion to yourself and everyone, as you would naturally show love and compassion to a child.
