I reflect back 35 years ago, and look how far we have come in America with our environmental policy to improve the conditions of our air and water, and we have had some real successes.

We had some major successes and we did so because the country embraced the spirit of Earth Day and embraced this concept that we have to have forward-looking, visionary environmental policy and energy policy in this country.

I'm proud of my work and how far I've come, and I'm proud of the way that I did it.

It's tragic from how far we've come from 'Hope and Change'.

When I was 12 or 13, I realised I was good, but I never knew how far I'd get.

People ask me how far I've come. And I tell them twelve feet: from the audience to the stage.
