I usually forget about it. If it's a good enough idea, my subconscious will remind me of it later, with a few of the kinks worked out. I've had enough ideas that made me jack squat because I didn't have the time/conviction/confidence to work on them. If you have lots of ideas but none of them are nagging you, you probably don't care about it enough to do a real startup. But that doesn't mean you can't use one of the other Eureka's as practice, and who knows? If you want more successes, fail more often. Make a cheap, bare bones v0.1 and find out what other people think. Now get to work!
