The Gap: animation of Ira Glass's inspirational rant about overcoming fear of creative suckage

My question is: When you’re still in the gap, what do you do with all that not-very-good stuff that you’re making? If you know your art is a failure, you’re not going to want to share it (this is particularly true of writing, where you’re asking the reader to invest a lot of time and focus)…but it’s also not very rewarding if all you do when you finish a project is save it to your hard drive and move on to the next thing.

Where is the reward system that motivates you to keep creating while your work is still sub-par? Or is it just 10,000 hours of delayed gratification?
