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. You can seduce yourself with your gifts if you're not careful， and if you do， it'll probably be to the detriment of your choices.
选择比天赋更重要 今天我想对你们说的是，天赋和选择不同。聪明是一种天赋，而善良是一种选择。天赋得来很容易——毕竟它们与生俱来。而选择则颇为不易。如果一不小心，你可能被天赋所诱惑，这可能会损害到你做出的选择。
