I had looked at this for several months before I decided to try it. I have tried various things, and could never motivate past 1 week. I was never excited about it. But I find myself consistently exciting about getting out there. I promised myself, if I did 2 weeks then I would buy new shoes. I was just using a very cheap pair, and my ankle and knee have been kind of touchy the last couple of days. I went to my local running store tonight, bought a new pair of shoes, and finished week 2. I have cut my smoking by half, and Sunday is my quit date. I wanted to get started with exercise and find what I liked before I quit. It motivates me .
