Let them see that their words can cut you and you'll never be free of the mockery. If they want to give you a name take it, make it your own. Then they can't hurt you with it anymore.
Don’t wait until they tell you you are ready. The world might say you are not allowed to yet. I waited a long time in the world before I gave myself permission to fail. Please, Don’t even bother asking, don't bothering telling the world you are ready. Show it. Do it.
