Every creative act involves a leap into the void. The leap has to occur at the right moment and yet the time for the leap is never prescribed. In the midst of a leap, there are no guarantees. To leap can often cause acute embarrassment. Embarrassment is a partner in the creative act - a key collaborator. If your work does not sufficiently embarrass you, then very likely no one will be touched by it.
