My focus

Ok, I have just racked my brain trying to think of something that would be a good "deadline" for me; I'm not really into the competition thing, if I could find a sport around here to get into, I would be interested, but I can't run, its physically not possible for me; I swear I twist my ankle every time I do, and I've always been that way. Even in high school. So, I'm focusing on the personal trainer thing, with the nutrition thrown in there, and of course, no one wants a fat personal trainer, but I couldn't think of how to put a deadline on that (once you pay for the course, you get 2 years to complete it). So...I'm still working on it...
