Telling people who couldn't muster the sustained willpower to lose weight through diet and exercise that they "just didn't want it enough" is rude and unhelpful. It's a little bit like telling bereaved parents they didn't pray hard enough for their deity to save the child. I'm happy for you, and hopefully the advice you're giving isn't some form of willpower woo-woo. The hard truth is that you were lucky; none of us can truly account for why we did or did not succeed at a practically achievable long-term goal. If the other 49 obese people had the capability to will themselves to health, they would have done so.
