I've long suspected they're the same thing - or, at least, on a spectrum together. I know that I just don't "feel right" if I work less than I want to, or if I skip out on a workout session I had planned on. And I know that with myself and other people I train jiu-jitsu with, we will train with injuries that rationally we know we should not. When we talk about it amongst ourselves, we say things like "I just can't sit on the couch doing nothing." I suspect this "discipline" to get back to training is similar to obsession and compulsion.
