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.
You are given the gift of life in order to discover what your gift in life is. You will complete your mission when you figure out what your mission is. This is not a paradox. This is the way.
