I really liked how Alan put it ("analysis paralysis") but it nagged at me a bit that you (CL) know what to do; it's just a matter of getting it done. Then I read Ultralight's post and realized that this was it.
My college degree is in journalism. As students, we were responsible for producing news for the college's TV station. We all wanted to write Pulitzer-worthy news stories. But the reality is that, at 8:23 every morning, the news had to be on the air. We learned to do the best job we could in the time we had allotted to us. An accurate informative report at 8:23 was vastly preferable to several minutes of dead air or "Please Stand By" because we weren't done writing or editing the prize-winning version of the report. It was a good lesson for life. Give yourself the permission to prioritize the important stuff so that, in the end, progress is made. Make sure all you want to do is realistically do-able. But once you've determined that, move. You'll probably look back happily realizing all you achieved (even if it was not perfect).
