So instead of resolving to stick to a schedule for pursuing a particular project, I resolved to meditate every day and let the rest sort itself out. I have meditated sporadically for about 10 years, and always appreciated it, but recently had gotten out of the habit.
So far it's been pretty good. The productivity is coming more naturally, albeit in somewhat random bursts, but mostly I'm just more at peace with myself, which I think is more what I'm really after than anything.
