The worst trait a writer can have is impatience. This 'emotion' is the basis for almost all of the bad decisions made by a writer. I am well acquainted with impatience; we're old friends. Impatience leads to over-sight, over-stepping and over-indulgence. Those of us infected with this trait, often send out a story long before it's ready, and spends a lot of time wincing at the things that might have been.
I'd go into more detail about the cause and effect of impatience, but then you'd miss the point.
