The two best ways to expand the horizons of our children is for them to travel and for them to read. In traveling they can be exposed to unfamiliar places and also see both the bad and the good of how other people live. That allows them to learn firsthand that there are places in the world other than Newport Beach, and both be stimulated by the differences and more appreciative of what they have here at home. In reading they can vicariously live the lives of other beings of any time and any place, and this will in turn bring them a much deeper understanding of their own lives.
When I was 12 years old, my parents took my older sister and me to Europe for six weeks. We took the train from here to New York, and then a passenger ship to England. Our parents did it this way so that my sister and I could see firsthand how large our country is, and how far away Europe is from us.
