Always Be Revising

The ordinary writer is bound to be assailed by insecurities as he writes. Is the sentence he has just created a sensible one? Is it expressed as well as it might be? Would it sound better if it were written differently? The ordinary writer is therefore always revising, always chopping and changing, always trying on different ways of expressing himself, and, for all I know, never being entirely satisfied.
