My favorite quote:
"Losing weight after being fat for a long time seems like a monumentally impossible task, like climbing Mt. Everest, or in some cases, a flight of stairs. Either way, going from the way you are to being a "normal" weight can sometimes seem like a ridiculous fantasy. That's why when you succeed with changing one tiny habit, it can change your whole perspective. It's not this monstrous solid mountain you have to overcome, it's just a big pile of stones, and you just easily picked one up and moved it. It's not about heaving the whole thing aside with some supernatural effort, it's just about moving one stone at a time. And the first one wasn't so bad, so you're stoked to grab a couple more."
