One thing is just read all the standard advice out there from HN people, The Lean Startup etc. Also older stuff like The Mythical Man Month. Not exactly sure what you mean by come up with an idea. I have dozens of ideas and come up with new ones all the time. If you're always in the back of your mind on the lookout for a business, and your mind is active, ideas will come to you. Maybe you mean feasible ideas. I usually rank my ideas by how long v. 1 would take to make, and concentrate on the shorter ones. For example, I know Android, and wrote a stopwatch app in two weeks. It might be too easy to write, too competitive due to that ease etc. - but its just two weeks from my life. I've also written Android apps where v.1 took 2 1/2 months. The main thing I'd say is think how long v. 1 will take. Something like one year would be too long.
