不存在所谓的质量问题。只有人们没有做他们应该做的事情的问题。

"To love is to risk not being loved in return. To hope is to risk pain. To try is to risk failure, but risk must be taken because the greatest hazard in life is to risk nothing."

"It is a capital mistake to theorize before one has data."

成功不是成为最好的，而是激发他人最好的一面。

练习时多流汗，战场上少流血。
