To know a species, look at its fears. To know yourself, look at your fears. Fear in itself is not important, but fear stands there and points you in the direction of things that are important. Don't be afraid of your fears, they're not there to scare you; they're there to let you know that something is worth it.
I am my own biggest critic. Before anyone else has criticized me, I have already criticized myself. But for the rest of my life, I am going to be with me and I don't want to spend my life with someone who is always critical. So I am going to stop being my own critic. It's high time that I accept all the great things about me.
