A wise man once responded to my fearful exclamation of not being ready to reveal my hard work and extend the branches of my professional identity.  He said, "you will never feel ready, your head will want more and your heart will remain sensitive to the reaction of others.  Heck I've been doing this my whole life and am considered an expert in my field and I still don't feel ready!  But when you put your mind to it and do the best you can, you CAN do anything and you will surprise yourself.  If you freeze and do not permit the risk-- no risk will ever be taken and you will remain always hanging onto the idea and never experiencing its unfolding."
