The first answer is the best. Stick to a strict two or three week sprint or iteration. Assume any new ideas are bad ones and jot them down somewhere. It's important to sleep on ideas. So many times I think I've come up with something brilliant and unique; I buy domains, Google Apps accounts, start projects in Xcode, etc. As time goes on, I passively estimate the amount of work and level of potential success of the end product. Typically I come to the realization that idea doesn't seem worth it given all the calculations I make off the top of my head. "Idea overflow" can be avoided if you sleep on new ideas for a bit. The real issue is that there are seemingly no bad ideas; that is most seem worth pursuing in the age of uber's and snapchats and instagrams because success is a crapshoot. I think it's important to determine your end goal. Are you trying to make a very successful and popular app? Well, if that's the case then it's a crapshoot and you'll have some sort of productivity schizophrenia making every, single, app that comes to mind. Alternatively, is this idea something that you personally need? that would increase your personal productivity? something you're not focused on other people using? I'd sleep on that a bit or do some research to see if it already exists. I think it's important to qualify "good" ideas vs "bad" ideas. This way, the idea firehose can be tamed. In my mind, good ideas are an intersection of something you would personally use, that adds value to your life, and something you think other people may get use out of as well. Another good idea is one that makes you healthier; either mentally, physically, socially, spiritually even. With any idea, you should ask why you would want pursue it and how would you feel after completing it? Pursuing creative interests is important, but it's also important to identify why you're doing what you what you're doing.
