世界上没有一样东西可以取代毅力，才干也不可以——怀才不遇者比比皆是，一事无成的天才也到处可见；教育也不可以——世界上充斥着学而无用、学非所用的人；只有毅力和决心，才能无往而不胜。

Nothing in the world can take the place of Persistence. Talent will not; nothing is more common than unsuccessful men with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated derelicts. Persistence and Determination alone are omnipotent. The slogan “Press On” has solved and will always solve the problems of the human race.
