世界的美有两面，一面是欢笑，一面是痛苦，将心切成两半。
The beauty of the world has two edges, one of laughter, one of anguish, cutting the heart asunder.
The only real prison is fear, and the only real freedom is freedom from fear.
The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.
Gratitude will unlock all other virtues and is something you can get better at
事实就是真实的思维。
