one thing I'm not too lazy about
Somehow I'm not completely lazy when it comes to exercise.
It helps that I join a lot of sports teams, which usually guarantees at least 1 weekly watch. But I've actually more or less maintained a jogging routine for the last 3 years. I have had slips where I've gone a couple months without jogging, but I'd estimate that between sports and jogging I've exercised at least 3 times a week for 50% of the weeks in the last 3 years, and at least 1 time a week for 80% of that time.
At various times in my life I had tried to pick up jogging but I absolutely hated it. I actually was on a track team for 2 years in maybe 7th and 8th grade, but I hated every minute of that too. But for some insane reason I started running again when I moved into this house, and I've stuck with it.
Mario's deadline theory is good, and I find that it accurately explains a lot of my behavior. But it doesn't explain jogging. I think inertia does.
What I've found is that once you get over the initial hump, regular exercise really feels good. You start to enjoy it and you just want to keep doing it. Aside from the more obvious physical benefits, being in good shape seems to help in lots of little ways. I sleep better - falling asleep more quickly, and waking up more easily after less sleep. When I was playing poker, I noticed I could concentrate more intently and play longer sessions. I think my mood is better when I'm in an active phase, which my girlfriend would probably corroborate. Whatever happens to your muscles a few hours after you use them feels really good, like some kind of natural drug. Plus I drink lots of Gatorade, and it tastes awesome.
So maybe there are other things in life that are self-perpetuating like exercise. But getting over that first hump does take a lot of willpower. But it kind of gives me a little hope, because I've been able to keep up with it, and the more I keep up with exercise, the little side benefits could probably help with other stuff. Better sleep gives me more hours I can be productive, and better attention span and concentration helps there too.
