U-pun my word, my title is serious. Habits are very serious things indeed. Without them, we would have to figure out certain actions anew each shining or foggy day. I suppose memory would help, but morning routines would be matters for attention, rather than things to be done on autopilot while planning the day. So clearly habits are not all bad; in fact, they make orderly life possible. And habits do come in series -- one leads to the next, and they supplement each other. We have a series of actions to get us up and cleaned and dressed and looking our best for whatever sort of day we see ahead. Then another series gets the car out and down the driveway and navigating the morning traffic. We can arrive at work having forgotten a very important errand that we intended to do on the way, but which was not a part of our usual routine.
Other habits cannot be regarded as good without some thought. We can gradually stay up later and later, and acquire all the ills of sleep deprivation. We can consistently stop in at the bar on the way home for a few drinks and some fried food, without consideration for calories or a history of family heart troubles or the possibility of having to breathe into a police machine for a routine alcohol check.
Clearly bad habits are hard to change, but good habits are wonderful. At the very best, we can put a good habit into the place of a bad one. The worst option is to pay habits no attention, and they will indeed look after themselves.
