You can't get to the top by being nice.

The truth is that we are all alone in the world.

The most effective policies are those that align individual and collective interests.

The only way to do great work is to love what you do.

We are all of us made by what we have done, and what has been done to us.

I don’t like to be forgotten. I like to be remembered.

发现的喜悦无疑是人类心灵所能感受到的最活跃的。
