I'm less quantified than I could be, but enough that it makes a big difference over "nothing." I log hours on Joe's Goals; I have to count distracted hours the same as focused ones (what else would I do?) but I make up for it by also counting tasks completed.

Sleep I don't log regularly, except that now I notice what time I go to bed (I didn't before!) so that I'm actually aware of how many hours I sleep a night.
