The house should be a temple of the family.

If you do not tell the truth about yourself you cannot tell it about other people.

Not for the sake of our health, though it's often presented that way, but because it's an escape from the human anthill. It's an escape from our own competition, and our own dramas. And that's why ween joy looking at glaciers and oceans, and contemplating the Earth from outside its perimeters, etc. We like to feel in contact with something that is non-human, and that is so deeply important to us.

If you only read the books that everyone else is reading, you can only think what everyone else is thinking.

保持信念。
