To keep going with realizations...

I do not care about what other people think anymore.
No, wait, actually, I do, of course, but when I meet new people, I am not that nervous anymore, and I do not watch myself hoping I won't do something stupid that will ruin everything - not anymore.

I guess when you know who you are, you don't become the person the others see you as. If some people think you are stupid, you don't have to be stupid anymore.

Or maybe when you've been so stupid and hated by whoever, you reach a limit and then you can't become worse.

I don't know.
