You ever notice how commitment is lacking in a lot of people? Tired of your hobby? Get a new one. Tired of your job? Get a new one. Tired of your house? Get a new one. Tired of your spouse? Get a new one. It's getting to be rather annoying, personally. Have we, as a society, become so lackluster in our emotions that we can't get our souls involved in anything anymore? So, it isn't fun anymore. So what? Is that why you did it in the first place? When you do something with all your soul (whatever that something is), you don't necessarily do it because it's fun, or because you're enjoying it. You do it because a) you know the prize at the end is more than worth the pain you're currently experiencing and b) you made a committment to do it, even if it's only to yourself.
I've started running in the mornings, a little bit each day. The goal is eventually to be able to run for 30 minutes straight. This week I'm running for five minutes at a time.
You never realize how long five minutes are until you actually try to run for that length. By the end of it, your lungs are on fire, and your legs are burning, and you're gasping for air, and you have stitches in your side. And on top of it all, I don't have the stop watch that tells me how long I've been running. My buddy has that. So in addition to being in pain and gasping for breath, you don't know how much longer it's going to continue. The only thing that keeps you going is the fact that you made a committment to run, and (provided you don't sprain your ankle or do something similar) you're going to see it through.
I know that eventually, I will obtain a fitter, slimmer body. Or at least, that is what I hope. And that is why I run. I don't run because I enjoy getting up early in the morning, nor do I do it because I enjoy gasping for breath or shooting pain up my legs. None of that is what I call "fun." It cerainly isn't what I would call a good time. But that isn't why I do it. I run because I know what I'll get out of it. But more importantly, I made the commitment to do so.
Just a thought.
