????You can always do what you should do if you're willing to put in the time and energy to develop a new set of skills. If you only extend into places where your skill sets serve you, your skills will become outmoded.

????只要你愿意投入時間和精力來培養新技能，那么你就能做你應該做的事。如果你只涉獵你能力所及的領域，那么你的技能就會過時。

????─杰弗里·貝佐斯（Jeffrey Bezos，亞馬遜公司首席執行官）
