"I think there are few opportunities for one person to really influence history. The opportunity is very rare. I think that even if you become a president, you won't necessarily be able to change history. But if you give people a new, important way of thinking, this thought itself can change the world. And if you want people to heed your thought and believe in it, you should practice it yourself. Also your character, personality, and ability are central to people's belief and trust. A liar will never win anyone's trust."
