What I want to talk to you about today is the difference between gifts and choices. Cleverness is a gift， kindness is a choice. Gifts are easy -- they're given after all. Choices can be hard.

译文：一心想求取科举功名的人，不一定能体会到琴棋书画的乐趣；追求生命境界的人，不能没有经世济民的才能。赏析：读书或做事，我们不能总是带着功利性极强的目的去。目的越强，中间的乐趣无法体会，其结果往往事与愿违。如果我们抱着一颗平常心，往往会有意想不到的收获。那些道德品质高尚的人大多博学有才，他们用自身的言行去改变周围的人，去改变这个社会。
