The thing that helped me, when I felt the indecision paralysis come on, is to just do something and accept that it may be wrong. You often don't know the best decision in the first place because you lack experience. Doing it the right way by accident, or making the mistake of picking the wrong way helps get you that experience. Be deliberate about always doing something, and over time the paralysis will get less and less as you gain more experience.
Well-stated -- and (at the risk of over-complimenting), very close to the absolute zen of self-driven learning.
