Going off the calendar thing -- some years back I managed to lose a ton of weight and be super productive; I had this little system where every day I would try to keep the number of vices I had that day to less than half. For example, if I smoked a cigarette and ate poorly, to keep that day at 50% I'd need to exercise and do (home or project) work done. If there was a day where I didn't want to exercise, I'd have to do at least 2 of the other things. Like most people in this thread, I know I can't trust myself to be perfect, so I give myself outs. I can do whatever I want, so long as I pay for it elsewhere.
