Success is not about the money you make, it's about the difference you make in people's lives.
成功不在于你赚了多少钱，而在于你对人们生活的影响。
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.
The best way to find out if you can trust somebody is to trust them.
