Already people are saying we do need a change.
As long as I feel I am doing what I think is right and just for my country, for the Greek people, that is enough for me.
I will always be upfront with the Greek people, so we can solve the country's problems together.
It is important that the Greek people make decisions on important developments.
People would say you look weak if you're not cursing the opposition and driving around in a big black car while always wearing a tie. Above all, to be 'strong' you're always supposed to be giving orders.
Politics also means educating people. It's important to speak openly with our fellow Greeks, to tell them what our problems are and that we have to change something.
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 polarisation and the barbarism of dictatorships - that made me feel that we had to change this country.
Unfortunately, corruption is widespread in government agencies and public enterprises. Our political system promotes nepotism and wasting money. This has undermined our legal system and confidence in the functioning of the state. One of the consequences is that many citizens don't pay their taxes.
This idea that you're a successful tough guy if you evade taxes and deceive the state has got to change.
We stand united, facing the big responsibility to change our country into a nation of justice, solidarity, humanity and green development.
We are a country with great potential. We have the political will to make deep changes in a just and equitable way, to put our country back on a development path, to meet the challenges of a new world.
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.
There are certain moments in the history of a nation when the choices made define the decades to come.
There is this concept of politics as a dirty game.
I never thought of politics as a profession.
