My motivation comes and goes. I'll quit smoking for a few weeks and train hard. I'll start to see results and start feeling good and then I'll just stop. I'll start drinking and partying alot and chain smoking. I always revert back to my old self. Honestly I'm probably clinicly depressed or clinicly something. Sometimes it's like I'm on the ball and other times I'm just off. When I'm on I'll go home and cook for myself, clean my house, keep my car and bikes clean and maintained. When I'm off I'll go home and sit in front of the tv watching Discovery or The History channel and smoke a pack of cigarettes. Sometimes I can go to bed and get seven hours sleep and get up and run or work out on the bag and other times I can't go to sleep till late and then don't want to get up in the morning. I see the same kind of cycles in others I know. I just thought I'd ask here because serious martial artists have always struck me as an exspecially driven group of people. What drives you?
