Afraid

This question has been asked to me many many many times. I should be familiar with this situation but deep down i know i am scared, afraid, fragile. I guess a broken glass will not fully be new even after patching. Each time i feel as if asked to jump from the cliff. My parachute may or may not open or maybe i may not need it. Some told me i should just enjoyed the journey, the process, the sweetness, the sour, and all of the above. But WHAT?? What is holding me back?
