What keeps you going?

I'm interested to know, what keeps you turning up to training? Continuing with the sport? I know some of you are probably pro fighters, hobbyist fighters, or just enjoy sparring and training.

I myself have been training for six years now, and have the privilege of training with some elite level fighters, world champions, and get to spar with them regularly. But I'm 40 years old now and not sure that I'll have a fight. I go through weeks where I wonder why I'm still going, as most of the people take it much more seriously than I do. Then I'm reminded how much I love it.

So what keeps you turning up, even when you don't feel like it some weeks?
