I've also gotten some perspective by realizing that what was The Perfect Story Oh How Will I Ever Be Good Enough To Write This say, three years ago, is now all but forgotten today unless I go back through my archives. Not always, but more often than not. So just because something seems Incredibly Wonderful to me now doesn't mean I should wait to write it, because it might not seem all that shiny after I've had more experience.
Don't wait to be perfect
If that makes any sense.
