How to get that BIG project done already

I was originally hoping to write this in July, then I pushed it to August and then to September but here we are in October and its finally here. Sometimes my projects get pushed down on the priority list - even when they are very, very important. Does this ever happen to you? You have a big idea, a strategic project that will be so impactful once done. But if you are like any other super busy, overwhelmed professional you can't seem to get to it.
