The Sky is the Limit

Sometimes I'm afraid to take out my camera and takes pics. I'm not sure why, I feel the same struggle sometimes to write or to be creative in general. I'm not sure why, am I afraid of failure? Is it even possible to fail at expression? What is it that keeps me from putting the pen to the pad when its just me, alone with my thoughts. Why can I not seem to just push the button and see what comes out on the other side of this moment...?
