As soon as politicians start climbing up the ladder, they suddenly become kings. I don't know how it works, but what I do know is that republics came to the world to make sure that no one is more than anyone else.

No country can solve climate change alone, we have to take global measures.

In life you can fall down 1000 times but the point is to have the willingness to stand up and to start again.

A president is a high-level official who is elected to carry out a function. He is not a king, not a god. He is not the witch doctor of a tribe who knows everything. He is a civil servant. I think the ideal way of living is to live like the vast majority of people whom we attempt to serve and represent.

What's sad is that an 80-year-old grandpa has to be the open-minded one. Old people aren't old because of their age, but because of what's in their heads. They are horrified at this, but they aren't horrified at what's happening in the streets?

We can almost recycle everything now. If we lived within our means, by being prudent, the 7 billion people in the world could have everything they needed. Global politics should be moving in that direction. But we think as people and countries, not as a species.

What was my great sin? To have revealed the private property of the bank - well if this is being a criminal, then maybe I'm a great criminal.
