If people are not smoking, they'll probably be drinking more.

Look at all of the great strengths of America: entrepreneurialship, work ethic, natural resources, a democracy, a transparency, a willingness to be critical. Around the world, they look at us, and they say, "Why are you criticizing yourself? Why are you people arguing during the political process to elect a president or somebody else?" That's the great strength of this country.

I think that most of the candidates [for presidency] can't run the railroad, and I still worry that whoever gets elected will have policies designed for political rather than practical reasons.

The mistake that was made in the '70s is we stopped policing the streets, we stopped cleaning the streets, we stopped cleaning the graffiti off buildings, we stopped supporting our cultural institutions and building parks and schools and all those kinds of things.

If a hurricane strikes, we can blame the president for not being there; we can blame Congress and FEMA; we can blame the state governments; but in the end, it's the mayors and the local city governments that have to be prepared for emergencies and be prepared to act.

Design does matter. And not necessarily in a way that people realize. A lot of what you do, people take for granted - that a park has always been here, that a bicycle lane has always been there, that the street is safe or clean.

Most people won't have opportunity to do full-time service, but those lucky enough to have monetary wealth or some spare time really can make an enormous difference. As someone who's now in the public sector, and is seeing up-close-and-personal the real impact of what we do and what we give, I can tell you: every dollar and every volunteer help, in more ways than you can count.
