I do something similar. I have a few rules for myself right now. Mostly:
* Work on my book[1] every day.
* Exercise twice a week.
* Run every weekend.
* Then a few ones around what I eat.
I allow myself to tune those rules over time to better optimize what I'm going for, however I don't let myself change a rule right when it's in play. If it's Sunday afternoon and I haven't run yet, I don't get to decide if I'm going to change my running schedule. Past me set that rule, and present me must follow it.
After I run, I can consider tweaking it. But, then, of course, I find that after I've run, I feel pretty good about it and end up sticking with the rule.
