Normally I keep my "must do" list in my head. Occasionally the list gets too big and I can't remember it all, I write it all out in TextEdit and leave it open and delete lines as I finish items until the list is empty. I only do this for important items; (i.e wishing your best friend happy birthday) If items are unimportant then its not too big a deal if I miss it today (i.e add X to your website), as long as its not deadlined of course.
