Two of the most important things when it comes to weight loss are motivation and dedication. You have to want to lose weight to an almost emotional degree, and the dedication to keep at what you need to do to continue to lose weight even if your body starts to create excuses.

It's hard to get people inspired to do so though. It's often something that person has to become driven to do.
