Yes, I also find it very easy to get overwhelmed when I realize just HOW long my "to do list" is... and I spend more time organizing and restructuring the list than actually working on it!

Much as I am not big into this kind of goal setting, I do find that writing things down helps me set priorities... and I often have to admit that I am putting too much effort into low priority things, rather than those that really need to get done. And then I end up — as I am, at the moment — suddenly having to pull all-nighters because I didn't get a bunch of my bookkeeping for taxes done... a LONG time ago!
