The key to keeping up motivation is some sort of success or reason to think you'll be successful. In the beginning, us entrepreneurs are filled with confidence (or dillusions depending on how you look at it). It's this confidence that keeps you going. But, as reality sets in and no one uses your app, you begin to realize it's not going to work.

I guess thats why they always recommend release soemthing early , so you can get some small measure of success: at least get some positive feedback to validate your idea.
