If you love people, you'll enjoy your life. If you don't, you won't love anything you do.

Every time I jog through the world, I am awed by what I find. On a winter morning, when it seems too cold and slippery for safe jogging or bicycling, I can still go out and experience the glory of sunlight turning icy branches into strings of sparkling diamonds.

I love how Mother Theresa said she wouldn't attend an anti-war rally but if there was a peace rally to call her. So I realized it's not about waging a war against everybody's disease and diagnosis but rather about helping them live.

Be grateful simply for being alive. When you are grateful for life, pure and simple, your life becomes one you can be grateful for. That may strike you as circular or even backward logic, but your attitude really does have an effect on how things work out. When you can't change your life any other way, you can still change your attitude. When you do, your life changes. You find more chances to love, and you will be surprised to see how much more love is returned to you.

Medicine is a very tough thing. I mean, everyone is going to die. Sooner or later. That's a tough thing to face.

Do not be afraid to love. Remember dear old Don Quixote, viewing the world with love. He saw many beautiful things no one else saw. Try being dear Don Quixote for a day. You'll see that love improves your vision and allows you to see more than your eye has ever seen before. But be forewarned: Those who look on the world with love will need a handkerchief, not to use as a blindfold, but to blow their nose and dry their tears.

If you see what you do each day as your way of loving the world and helping it heal, then life gets to be a lot different. The difference between burning up and burning out is the difference between loving what you are doing and not loving it.
