I have, and I am sick of it. No doubt it has caused me to act out in all sorts of ridiculous ways and make a complete fool of myself. I admit it, yes. Because I don't think I should have to respond to the behavior of others rationally. They don't deserve it.
I have nothing to prove to anyone. I had nothing to prove to anyone when I was eight years old or sixteen or twenty-one or thirty-five, forty-five, etc. except my wife and kids.. when you get married you make promises, when you have kids you make even bigger promises... I owe my employer a good day's work. But there it ends. My duty ends with my responsibilities.
Outside of the people in my life, the people that I love, I owe nothing, and I certainly have nothing to prove.
So why is it that so many people expect you to prove something? Maybe because their lives are so shallow and empty. I keep trying to comfort myself with that thought, the same way I tried to comfort myself as a child by realizing that the kids who bullied me were more miserable than me and it doesn't help at all.
