Causes do matter. And the world is changed by people who care deeply about causes - about things that matter. We don't have to be particularly smart or talented. We don't need a lot of money or education. All we really need is to be passionate about something important; something bigger than ourselves. And it's that commitment to a worthwhile cause that changes the world.

The first secret of success: Believe in Yourself. Nothing changes in your life until you believe you can do things that are important to you. And if you have a low opinion of yourself, nobody else is likely to raise it.

Let go of a need for personal recognition. Heap kudos on others and they'll perform even better next time. Leaders are only as good as those who follow them and followers are at their best when leaders are quick to give credit for successes.

You have a great body. It is an intricate piece of technology and a sophisticated super-computer. It runs on peanuts and even regenerates itself. Your relationship with your body is one of the most important relationships you'll ever have. And since repairs are expensive and spare parts are hard to come by, it pays to make that relationship good.

Leaving what feels secure behind and following the beckoning of our hearts doesn't always end as we expect or hope. We may even fail. But here's the payoff: it can also be amazing and wonderful and immensely satisfying.

Learn - improve - grow - live. Learn as if you might live forever and you'll live as if you might die tomorrow.

An authentic and genuine life grows like a sturdy tree. And like a tree, it grows slowly. Every time you make a different and better decision, it grows a little. Every time you choose to do the right thing, even when nobody would find out otherwise, it grows a little. Every time you act with compassion, relinquish your right to strike back, take a courageous stand, admit fault or accept responsibility, it grows a little.
