I am easily motivated by rewards. Rather than food-based rewards, which would be bad for a diet, WW uses charms. Charms are given for weight loss milestones. Charms are given out in meetings, and not available for online-only members. Because I am easily motivated by rewards/awards, I wanted charms despite not initially attending meetings. So I bought them on eBay. That kept my motivation up and gave me something tangible as a reward for my weight loss.
