Writing is about communicating. Redrafting is intended to allow better communication. Better communication is not a waste of time.

Perfectionism is a form of insecurity. If perfectionism leads to capitulation rather than communication, there is a problem.

Not every communication has to be perfect. Most times the communication is more important than the frustration that perfectionism engenders. Recognize not every communication requires the attention of a dissertation and get on with it.

Good luck.
