I'm really guilty of spreading myself too thin with projects. Recently I asked myself a different set of questions to evaluate what projects I wanted to work on, and it made deciding very easy:
1) Which ideas can be turned into a company?
2) Which have the most attractive success scenario?
I spent too much time focusing on any idea that could make money. Well, the problem is that making money really isn't that hard if you know how to ask for it. Every idea that came into my head was good enough to work on - if you ask yourself question number 1 a lot, you'll have the same problem.
Once I started focusing on question 2 everything became much more clear. You have to ask yourself a lot of questions to get to an answer; the questions (and answers) are far more personal than you can ask advice about. If you're going to give up a significant portion of your time to succeed, it's important that there's a big enough payoff for you at the other side. For some people, this is purely financial; some people want to make "popular" software that everyone uses. There are people who just like working on interesting problems, and people who really just want a day job where they can be "the boss".
If you decide what's most important to you, it should be much easier to decide what to work on. You'll end up with the added benefit of being much more motivated to work towards a goal that is desirable to you; not one that everyone else thinks is desirable.
