When Did It "Click"? What Made It Stick?

I'm curious to know what motivated you all to begin this journey of weight loss and getting healthy? What has motivated you to stick with it? Was it a family member? TV show? Health scare?

For me, the realization hit me a few weeks ago that this is something that I will struggle with my entire life. For what seems like forever, I've been telling myself that I only have to be "good" for long enough to reach my goals, and then after that I'll be able to relax again and slip right back to my old ways. But that's not true. I've come to realize that whatever changes I make while I'm on this journey, are changes that I need to make a part of the rest of my life. Accepting that has made this process more permanent to me, and that's actually made it easier. I've started to see this as a health-change, instead of merely weight-loss efforts.

So, how about you? Willing to share?
