○ Skeptics and cynics with limited vision who can only see the obvious reality can never solve the many problems of the world. We need those who can dream of things that have never existed.

○ Imagine thinking that doing things the same way will solve the problem. Then there would be no problem. But that's impossible. To solve problems in a complex and diverse reality, you need to come up with ingenious ideas that seem absurd. Even if those ideas are useless, find at least one solution from within them.

○ I don't care what you do. But whatever you do, be the best. Even if you become a sewer worker, be the world's best sewer worker.
