What does it mean to be confident? I think I finally found the answer to holding up my own.
We all want to be perfect. We want to appear so perfect that nobody can find fault with us. So when that happens, when someone points out a flaw, a person will crash down even if everyone else is telling them they're beautiful. Because not everyone is telling them that. If one person says "ew" out of nine hundred who say "wow" then the perfection is shattered. People get defensive about their imperfections. People don't LIKE that illusion broken.
I have learned to accept my imperfections. I recognize I have flaws. Everyone has them. I'm still a fortress, but the walls have holes that let insults pass through and come out behind me without touching me because I know they're there. Instead of being angry, I just acknowledge that someone said something petty and move on, thinking, "yes, I'm aware of that. And?"
I wish I knew that in high school.
