I have a similar attitude of procrastination and overplanning. My solution is to go really aggressively overboard with the planning, I create big outlines of all the necessary steps, in a fractal way, until I arrive at all these small things that can be assembled later. Then I start with the ones that promise some fun, and fill in the rest. Having said that, a lot of that doesn't get completed still. Procrastination isn't always bad, it can also tell you that something isn't actually necessary or promising. So if that sets in after the first steps, I'll happily abandon the project. Usually projects that include external feedback or motivation won't get abandoned that easily, obviously.
