One of the simplest techniques I use and have written about is simply limiting my goals to three. These are bigger type goals not NAs or to-do items. I read years ago in Inc. Magazine an article on the Marine Corp Rule of Three which limits the amount of "things" a marine has to think about. If this was increased to four effectiveness plummeted.

I have found the way to get lots of goals accomplished is to limit the list, actually get the goals accomplished and move onto another list. So instead of a laundry list of ten or more goals you have three but work through several lists and get more done. If the goals are really big ones like start a business, or get an advanced degree, they will be on the list for a long time with only a few other goals, which gives the big goals the focus they need to get done. Good luck
