This is my year of transition from what I'm calling the second phase of my life to the third phase of my life. And I wanted to pass it along. What I mean by that is, in the first days of your life you're dependent on others and you learn. You're basically a kid, depending on your parents. In the second phase of your life, you're working and others are dependent on you and you're trying to be successful. And then when you go to the third phase of your life it's no longer as much of a kick to be successful. There's a natural, instinctual desire to help other people be successful.
