Excitement about things became a habit, a part of my personality, and the expectation that I should enjoy new experiences often engendered the enjoyment itself.

I think if I were reading to a grandchild, I might read Tolstoy's War and Peace. They would learn about Russia, they would learn about history, they would learn about human nature.
