the question is, do you have to like it to feel successful?

I agree with Dilbert...
I don't dread working out at all, but I definitley talk myself into going in the beginning.. but something happens half-way through my long-runs, and I get really pumped up and then book the last half of the run...by the time I am finished... I am SO freakin' glad I actually did the workout. It's a strange thing.
On a side note, if I dont work out I typically feel pretty crappy.
