The problem is what to build. You're over-thinking things. Easiest actionable advice is to build whatever excites you. A great way to do this is to build something that would have at least one user: you. Maybe it's "just" something "cool" or maybe it solves a pressing problem. Don't get caught up in all of this up-front analysis where you try to build the perfect thing timed with some magical market moment. Instead, build a quick prototype if and when you feel excited about an idea. If your enthusiasm wanes early or you finish it and you realize it's not going to work out, it's OK ... wrap a bow around it and move on to the next thing. edit: You seem to be looking for a magic bullet in the form of a Paul Graham essay.
