I never thought about becoming a politician. But during the military dictatorship, my grandfather was put in prison six times and my father twice. If my family and my country didn't have this history, I might be a professor somewhere today.

If you put all the European countries together, we are the biggest economy in the world.

There is this concept of politics as a dirty game. It's a difficult game, but it doesn't have to be dirty. I think this is what we need to bring to politics. I think politics around the world has very often been captured by big interests - 'lobbies' they call them in the States.

I never thought of politics as a profession.

This idea that you're a successful tough guy if you evade taxes and deceive the state has got to change.

At times of distress, we all like to recall the advice of fathers and mothers. The best advice my father gave me was to keep faith and deep confidence in the potential of the Greek people; nurture the belief that they can do things.

If Greece had gone through a very normal political life, I may have not been in politics. But just the fact that I lived through huge upheavals and very difficult struggles and polarization and the barbarism of dictatorships - that made me feel that we had to change this country.
