This is so true, works on personal level also.

How many of you has boasted to your friends "I'm working on this cool new software, I'll have a beta in few months to show you", and this was already five years ago and you never did release anything? I have.

The best itches are kept closed until you have something to release. Then you can maybe tap into that other drive, where having users testing and depending on your software keeps you going.
