I don’t think I have any specific habit that I turn to in order to help my day-to-day activities. I sometimes take a vitamin pill, does that sort of thing count?
What I should do is exercise more, but that requires a level of motivation that I just don’t feel. I’m pretty sure daily exercise would do me a world of long-term good, but I don’t think I can work up the desire to do it. Perhaps that will change one day, but not today!
