"When you write something telling people to be good, you seem to be claiming to be good yourself. So I want to say explicitly that I am not a particularly good person. When I was a kid I was firmly in the camp of bad."
Having read and forgotten most of his essays over years, I could recall this in a minute. So probably there's more.
His lack of self awareness is incredibly impressive. I'm almost envious.
Don't know where i got it from. I usually use it as a reminder that even evil people like Hitler consider themselves as the good hero. Maybe in difficult circumstances. I don't want to compare PG to Hitler though.
Not to be sociopathic, but try to be the hero of your own story as well. Focusing on the things you do right and not remunerating on your mistakes it's a key part of mental wellness.
