I've seen some springs that ended up being terrible winters. We human beings are gregarious. We can't live alone. For our lives to be possible, we depend on society. It's one thing to overturn a government or block the streets. But it's a different matter altogether to create and build a better society, one that needs organization, discipline and long-term work. Let's not confuse the two of them. I want to make it clear: I feel sympathetic with that youthful energy, but I think it's not going anywhere if it doesn't become more mature.

I may appear to be an eccentric old man... But this is a free choice.

This is a matter of freedom. If you don't have many possessions then you don't need to work all your life like a slave to sustain them, and therefore you have more time for yourself.

It has always been like that with changes. In 1913, we established divorce as a right for women in Uruguay. You know what they were saying back then? That families would dissolve. That it was the end of good manners and society. There has always been a conservative and traditional opinion out there that's afraid of change. When I was young and would go dancing at balls, we'd have to wear suits and ties. Otherwise they wouldn't let us in. I don't think anyone dresses up for dancing parties nowadays.

From afar, it seems like a war without a solution and like a long sacrifice for the entire country. So when a president appears who tries to open a path to peace, I think that deserves support, because there is a lot of pain, and if they try to settle scores, the war will never end. But there is an opportunity. I would feel selfish if I did not help in any way.

My goal is to achieve a little less injustice in Uruguay, to help the most vulnerable and to leave behind a political way of thinking, a way of looking at the future that will be passed on and used to move forward. There's nothing short-term, no victory around the corner. I will not achieve paradise or anything like that. What I want is to fight for the common good to progress. Life slips by. The way to prolong it is for others to continue your work.

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.
