Renewable energy is proven technology, the price is dropping, the rest of the world is going that way, that's where our investment should be going as well.

Behind every successful man there's a lot of unsuccessful years.

I am aware that one should always make room for renewal in politics. A democracy is the healthier for the turnover of the depth of talent there is in its community.

Optimism is the staunchest worshipper of life.

I don't visit my parents often because Delta Airlines won't wait in the yard while I run in.

This idea of helping the next generation is a very intrinsic part of photojournalism. We need to continue to build this new group of photographers that come in and tell these stories.

I scream, you scream, we all scream... for the truth.
