I have a similar vice... I'm really good at planning things.
I've planned and then put together an awesome ultralight backpack, which I've used only a couple times in five years. I really enjoy tweaking it though, making it better. Turns out ultralight gear is useful for car traveling too. But I don't use it for it's intended purpose.
On the flip side, I work better from a plan. I recently spent several hours designing a crude electric guitar, writing step-by-step instructions on how to build it, then building it from those instructions. I'm almost done and the plan has kept me on track.
I have a tenancy to plan the crap out of things. Many of them I never complete; some I do.
You just summed up my third thing: organizing things instead of doing.
"I should really work on that project that's important to me, but I can't do it without 'clearing my mind' first. Better clean out my github/bookmarked reading list/workshop/garage/etc."
Turns out I'm really good at getting ready to do things.
