As human beings, our brains tend to default to the negative, and we're notoriously self-critical -- especially when something goes wrong. We think we're not good enough, not smart enough or not strong enough to achieve contentment.

"You are not your grades or your jean size or anxiety and depression," she says. "You are not your past. You're not defined by a number or a phrase or a moment."
Happiness isn't fleeting if you focus on the positive. Now that's a message worth believing.
