I personally tend to feel better after exercising. If my muscles are sore I just tell myself that this is the feeling of them getting bigger and stronger.
That said, I think I might understand where you are coming from. Here’s a hypothetical situation: Let’s say that the road that you live on is full of litter. One day you decide to pick some of it up. So you go out with a garbage bag and start picking up pieces of trash. Every piece that you pick up makes your neighborhood look a little better, so you keep picking up trash until you decide that you are done. This would probably make you feel better.
Now, let’s say that you committed some crime, and the judge sentenced you to community service, and you job was to pick up ALL of the litter on this road. Instead of feeling better about each piece of trash that you picked up, you would constantly be thinking about all of the trash that was left to be picked up.
I work on the weekends at a restaurant. At the end of everybody’s shift we have to do some prep work. Sometimes this is washing dishes. Now, if my boss said “Do all of the dishes and then you can go home” then I would look at the huge stack of dishes and be miserable as I worked on them. On the other hand, if he said “knock out some of the dishes and then you can go home”, then I would happily do each load knowing that I could technically leave any time that I wanted. I would keep doing one more load, and then one more, because the more I do, the less I leave for my coworkers. However, the fact that I can, technically, do as many as I want and then clock out makes me less stressed than if I HAD to do all of them. I might actually do all of them, in fact.
One more ancedote: I hate running. Always have. When I was in boot camp I never had a problem with pushups or situps, but the 2-mile run was a bitch for me. One time I was talking to a buddy about it, and I said something about how I just kept thinking “7 more laps, 6 more laps, etc…” He looked at me incredulously and said “Don’t look at it like that. Think ‘one more lap’, then ‘OK, one more lap’, then ‘OK, one more lap’,etc.”
I said all of that to say this: When I do work out, I don’t go in thinking “I’ve got to do 3 sets of this and 4 sets of that… etc.” I think “I think I’ll see how many times I can bench press this weight, and then I’ll see what I want to do next” If, after 2 sets, I want to do a third, then I will, but I’m not following any schedule, so I never feel like “Aw crap, I can’t wait to get done with this”, because I can quit whenever I want to. I usually choose to not quit until I can’t really do anymore.
I don’t know how you work out, but maybe it would work out better for you if you quit going in with a certain regemin in mind but instead just decided to work out until you were ready to quit.
