Ambition to work out..

Okay so I really want to go back to working out like I was in high school. I have a job which isn't an excuse. So my question is, to those of you who do work out, how do you motivate yourself?? I worked out religiously freshman through senior year. When I got a job I stopped because I was doing school, beauty school, and a job. Now all I have is a job where I can easily work out. I need help or inspiration!!!!! I used to be so fit and I can't stand my body anymore.
