Here is something fairly interesting that I have done. I started a couple weeks ago and it caught on. So everyday when I get home from school I do exactly 10 pull ups before I walk into the garage. It's easy, doesn't take a lot of time and I'm just pretty happy I've created this habit for myself. I don't even think about it anymore. I just see it as just a regular thing to do before coming home and it's just become a regular thing. Anyway, I've got to get to bed, I have a test or two tomorrow.
