How does one find the mindset to exercise?

I'm roughly 60 pounds over my idea weight. I have a stationary recumbent bike that I occasionally ride, but nowhere nearly as often as I should to lose weight. I'm well aware of the physiological benefits of exercising, and how detrimental fat can be. But I'm wondering if anyone knows of a web site or book or something that can help me to get into the proper mindset to do it on a consistent basis.

For comparison, I was wondering if there was something similar to Allen Carr's book on quitting smoking (which did wonders for me). Thanks!
