The biggest thing is to take a chance outside of your comfort zone.

It's something I don't advertise. It wasn't laying out on the table saying 'take me'.

I've been kicked out of school. It took me 30 years to get through community college.

It's really good for the students and I like to do it. I didn't travel much when I was younger. It [traveling] changed my life.

My great comfort is, that the temporary celebrity I have wrung from the world has been in the very teeth of all opinions and prejudices.

I believe there is a chance for progress if countries worried about services and market access can make some concessions and America and Europe can look again at agricultural protectionism.
