I'm an information gatherer. I dig around and find all the possible pieces of advice about the best way to do things before embarking on the journey. And often, I don't embark. Because I've already spent so much time learning and planning that I'm exhausted by the idea or I know entirely too much about why it will fail. I think the key thing is to strap on blinders and just do it. At least then you're making forward progress instead of sitting on a pile of hoarded (yet ultimately useless) knowledge.
