"Speculation is the most complete and magical game in the world. However, this game cannot be played by stupid people, by people who are too lazy to use their brains, by people with unsound psychology, and by adventurers who are trying to get rich overnight. If these people are rashly involved, they will be destitute until death. No matter who is born with a tendency to speculate, he should regard speculation as a serious business and be sincere and dedicated. ”
