If you believe you can change - if you make it a habit - the change becomes real.

I think I'm smart, and I know I was a good mom. But there wasn't a lot I could point to and say, that's why I'm special.

For a habit to stay changed, people must believe change is possible.

But countless studies have shown that a cue and a reward, on their own, aren't enough for a new habit to last. Only when your brain starts expecting the reward--craving the endorphins or sense of accomplishment--will it become automatic to lace up your jogging shoes each morning. The cue, in addition to triggering a routine, must also trigger a craving for the reward to come.

There’s something really powerful about groups and shared experiences. People might be skeptical about their ability to change if they’re by themselves, but a group will convince them to suspend disbelief. A community creates belief.

There's a natural instinct embedded in friendship, a sympathy that makes us willing to fight for someone we like when they are treated unjustly.

When people have a willpower failure, it's because they haven't anticipated a situation that's going to come along.
