The historian is a prophet looking backwards.

The more you read, the more things you will know. The more that you learn, the more places you'll go.

思考是智力的劳动，梦想是智力的欢愉。

The world is a place of chaos and confusion, and the only way to make sense of it is to find your own path through it.

做出伟大工作的唯一途径是热爱你所做的事情。
