Don’t let them say you ain’t beautiful. They can all get fucked, just stay true to you.

How wonderful it is that nobody need wait a single moment before starting to improve the world.

We are all in the gutter, but some of us are looking at the stars.

A lot of the things that will really improve the world fortunately aren't dependent on Washington doing something different.

The worst pandemic in modern history was the Spanish flu of 1918, which killed tens of millions of people. Today, with how interconnected the world is, it would spread faster.

Two out of every five people on Earth today owe their lives to the higher crop outputs that fertilizer has made possible.

Technology is unlocking the innate compassion we have for our fellow human beings.

Skype actually does get a fair bit of revenue.

When Ford sells a car, a dealer isn't allowed to take out the engine and put a different one in. When a newsstand sells the Washington Post, no one can go to the newsstand and pay them to rip out the classified section and put their own classified section in - if they could, they would do so.

You can't have a rigid view that all new taxes are evil.

I understand how every healthy child, every new road, puts a country on a better path, but instability and war will arise from time to time, and I'm not an expert on how you get out of those things.

The next time someone tells you we can trim the budget by cutting aid, I hope you will ask whether it will come at the cost of more people dying.

There's always been a lot of information about your activities. Every phone number you dial, every credit-card charge you make. It's long since passed that a typical person doesn't leave footprints.

By the time we see that climate change is really bad, your ability to fix it is extremely limited... The carbon gets up there, but the heating effect is delayed. And then the effect of that heat on the species and ecosystem is delayed. That means that even when you turn virtuous, things are actually going to get worse for quite a while. 

Should there be cameras everywhere in outdoor streets? My personal view is having cameras in inner cities is a very good thing. In the case of London, petty crime has gone down. They catch terrorists because of it. And if something really bad happens, most of the time you can figure out who did it.

People want to watch whatever video they want to watch whenever they want to watch. If you provision your Internet infrastructure adequately, you can do that.

There is no doubt that as an economy grows in a great way like India has, that you have to step back and change your tax systems, because you start to get more disparities of wealth.

If you count E-mail, I'm on the Internet all day, every day.

Eradications are special. Zero is a magic number. You either do what it takes to get to zero and you're glad you did it; or you get close, give up and it goes back to where it was before, in which case you wasted all that credibility, activity, money that could have been applied to other things.

I'm going to save my public voice largely for the issues where I have some depth.

Today, we're very dependent on cheap energy. We just take it for granted - all the things you have in the house, the way industry works.

Being flooded with information doesn't mean we have the right information or that we're in touch with the right people.

I can understand wanting to have millions of dollars; there's a certain freedom, meaningful freedom, that comes with that.

I've been very lucky, and therefore I owe it to try and reduce the inequity in the world. And that's kind of a religious belief. I mean, it's at least a moral belief.
