Big breakthroughs happen when what is suddenly possible meets what is desperately needed

Many of us who grew up playing golf know that our kids aren't doing it. A great way to enhance the game, make it cool again and bring back some of the interest among younger people is to make golf the greenest sport in an environmental sense. Every course's greenkeeper should think of himself or herself as the greenkeeper: responsible for preserving the green, not just the greens.

Several technological and political forces have converged, and that has produced a global, Web-enabled playing field that allows for multiple forms of collaboration without regard to geography or distance - or soon, even language.

There is a connection between energy, climate, food and political stability. That has played out in the Arab awakening and is not done playing out.

I think that competition will exist even if we discover more oil. We're never going to know how much we have, or how long will it last. You are always going to want to have diversity of supply. I think the Middle East will remain a region of competition, of global competition, fighting for a long time.

You always have to remember that Mother Nature is a lot like your body. If your temperature goes from 98.6 to 100.6, you don't feel so good. If it goes from 100.6 to 102.6, well, you call the doctor. If it goes from 102.6 to 104.6, you're in the emergency room at a hospital. The same with Mother Nature - small changes in global average temperatures have a huge climate effect.

We've given Iraq six months and I don't think things are really working out, so we should probably bring our troops home.
