"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."
