I work out every day. Hah, no I don't. I do work out most days, though. I didn't used to be a workout-every-day person. I got to this point through years of incremental changes and adjustments in my habits and attitudes.
People are impressed that I work out. They say, "I'm so impressed that you work out so often!" They say, "That's great, that you go to the gym every day!" It's one of the few things that I get randomly acclaimed for. (Of course, that says less about the magnitude of the accomplishment and more about what we value as a society.)
But valued or not, exercise is profoundly important. If there is such a thing as a panacea, it's not aspirin or vitamin D or fish oil, it's exercise. It's good for your body, it's good for your brain, and it's good for your mood. Apart from the actual doing of it, there is no downside to exercise.
That's the trick, though, isn't it? The actual doing. The taking time out of your day, the sweating, the special clothes. It's a bit of a drag.
If you want to enjoy the benefits of exercise, you need to minimize the drag. This is how I manage it.
