It took me a while to gain enough confidence to start thinking, "well I was ecstatic about this idea yesterday, so there must be something good here".
Now I try to remember specifically what excited me. Not as a bullet point, but as a vision. What was the cool task I imagined accomplishing? What was I thinking of when I felt like I had the right answer? Usually that's enough to get me back in the same state of mind.
But keep talking yourself out of ideas. That's the only way to get rid of bad ones. Just don't forget the good parts. Ideas evolve; let natural selection run its course.
