I tend to do something for two years then move on to something new. Yoga, then biking, then weight lifting, then back to biking. The moment it feels like a rut, I switch and search for a new love. It's like having a midlife crisis, but without the new wife or cheesy BMW.

On the day my daughter was born, I started writing a book for her. The plan was that, over the course of her life, I'd fill it with advice on how to be a strong woman. But along the way, I got caught up in the stories of Amelia Earhart, Sally Ride, and so many others. So how do you pick the best heroes for your kids?

If we live a self-directed, self-motivated, self-centered life, always needing to get our own way, then we're going to be miserable. In fact, many times we believe it's our problems that are making us unhappy when, in reality, it's because we're focused on ourselves!
