Looking back, if I had to live my life over, there are things I would do differently, but the one thing I would not change is my charitable giving. I'm particularly thankful for my father's advice to set goals so high that they can't possibly be achieved during a lifetime and to give help where help is needed most. That inspiration keeps me energized and eager to keep working hard every day on giving back and making the world a better place for generations to come.

Nuclear war would really set back cable.

I've never run into a guy who could win at the top level in anything today and didn't have the right attitude, didn't give it everything he had, at least while he was doing it; wasn't prepared and didn't have the whole program worked out.

To succeed you have to be innovative.

I don't measure success in numbers, but I consider my contributions of more than $1.3 billion to various causes over the years to be one of my proudest accomplishments and the best investment I've ever made. Those dollars have improved lives, saved species, fought disease, educated children, inspired change, challenged ideas and opened minds; at the time of my death, virtually all of my wealth will have gone to charity.

Even if we didn't have greenhouse gases, were going to have to move away from fossil fuels, as we're going to run out. They're finite, whereas solar and wind are infinite.

You can never quit. Winners never quit, and quitters never win.
