A business has to be involving, it has to be fun, and it has to exercise your creative instincts.

译文：月亮过了十五后，就逐渐不明亮了，人到了中年之后，做什么事都难以有大作为。赏析：青少年是人生最美好的时期，这个时期精力最旺盛，记忆力最强，也是人生最该努力奋斗的时候。

Never give up on something you really want. It's difficult to wait, but more difficult to regret.

每一个挑战都是让你变得更强大的机会。

Don't watch the clock; do what it does. Keep going.
