You don't have to say sorry for how you laugh or how you dress or how you do your hair or how you do your makeup or how you speak.
You DO NOT have to be sorry for being yourself.
Do that shit fearlessly.
This is you and you gotta spend the real of your life with YOU.
So start loving your sarcasm, your awkwardness, your weirdness, your peculiar habits, your unique sense of humor... your voice...your talents...your everything. It will make your life so much easier to simply be yourself.
