成为英雄的最大障碍是怀疑自己是否会证明自己是个傻瓜；真正的英雄主义是抵制这种怀疑；最深刻的智慧是知道何时应该抵制，何时应该服从。
The greatest obstacle to being heroic is the doubt whether one may not be going to prove one's self a fool; the truest heroism is to resist the doubt; and the profoundest wisdom, to know when it ought to be resisted, and when it be obeyed.
On motivation: "I strongly believe that missionaries make better products. They care more. For a missionary， it's not just about the business. There has to be a business， and the business has to make sense， but that's not why you do it. You do it because you have something meaningful that motivates you."
