应对不自由世界的唯一方法是变得绝对自由，以至于你的存在本身就是一种反抗。
"The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion."
This world is the best of all possible worlds.
I don't believe in pessimism. If something doesn't come up the way you want, forge ahead. If you think it's going to rain, it will.
"The more you read, the more things you will know. The more that you learn, the more places you'll go."
真相很少是纯粹的，也从来不简单。
The heart of the educator must be a living flame, a source of warmth and light.
