I'm not the poorest president. The poorest is the one who needs a lot to live. My lifestyle is a consequence of my wounds. I'm the son of my history. There have been years when I would have been happy just to have a mattress.

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.

Worse that drugs is drug trafficking. Much worse. Drugs are a disease, and I don't think that there are good drugs or that marijuana is good. Nor cigarettes. No addiction is good. I include alcohol. The only good addiction is love. Forget everything else.

But we think as people and countries, not as a species.

To live in accordance with how one thinks. Be yourself and don't try to impose your criteria on the rest. I don't expect others to live like me. I want to respect people's freedom, but I defend my freedom. And that comes with the courage to say what you think, even if sometimes others don't share those views.

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.

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.
