I start off the day shoveling my walk and clearing the snow and ice off my pickup. Why? Because it's fun? Because I like it? No. Because I have to get to work. Because I have to make a living. Because if I don't do those two things...I'll have to do other things that I like far less. I may not like going to work on a cold winter morning but I sure do like getting a paycheck.
Kinda the same goes for exercise. Do I like to exercise? Well, yes and no. I like the effects of exercise but I'm not really wild about the application. And, like going to work, it seems I can't get one without the other.
