人性中最深刻的原则是渴望被欣赏。
The deepest principle in human nature is the craving to be appreciated.
Science without religion is lame, religion without science is blind.
I will always be grateful to my poor parents. I owe everything to them, my education, my life, and any success I have had.
今天种下的每一棵树都是对未来的投资。
