I typically write mine down in a notebook. If its a really great idea, it doesn't normally just go away. You'll keep running into situations where it would be useful if the idea was already a reality. If after a week or two you still can't let the idea go, you "may" have a keeper. Get some feedback from friends and fellow techies - figure out which idea has the best chance of success and go with that. PS - Don't second guess yourself after you've made a decision. PPS - Don't undervalue the work you've already done on your current project. Execution is harder than ideation. PPPS - Lay off the coffee.
