So long as I can stay mentally alert - inquiring, curious - I want to keep going. I love my wife and my children, but I don't want to sit around at home with them. We go on safaris and things like that. I can do that for a couple of weeks a year. I'm just not ready to stop, to die.

We're starting with our own carbon footprint. Not nothing. But much of what we're doing is already, or soon will be, little more than the standard way of doing business. We can do something that's unique, different from just any other company. We can set an example, and we can reach our audiences. Our audience's carbon footprint is 10,000 times bigger than ours... That's the carbon footprint we want to conquer.

We need to push ourselves to make as many reductions as possible in our own energy use first - and that takes time. But we must do this quickly - the climate will not wait for us.

If you want to judge my thinking, look at The Sun.

Don't let's lose sight of what creates wealth. It is open markets, it is capitalism.

Everybody at home speaks mandarin except me.
