Infants and young children are not just sitting twiddling their thumbs, waiting for their parents to teach them to read and do math. They are expending a vast amount of time and effort in exploring and understanding their immediate world. Healthy education supports and encourages this spontaneous learning.

Play is not only our creative drive; it's a fundamental mode of learning.

I believe the important thing is to continue to create new experiences. That's why so many retired people travel. New experiences raise our consciousness and stimulate cognition. Retirement offers the opportunity to learn new things, and that is what keeps you young, at heart at least.

In leading-edge companies like Google and Apple, workers are given much freedom and opportunity to play. They know that's an important component of creating new and better products. I believe that at whatever level of work, cashier at a supermarket, janitor at an airport, aide in a cubicle, the addition of a playful attitude makes the job better and the work more enjoyable. A cashier or janitor who smiles and is friendly gets a better response than a surly one.

Many older wealthy families have learned to instill a sense of public service in their offspring. But newly affluent middle-classparents have not acquired this skill. We are using our children as symbols of leisure-class standing without building in safeguards against an overweening sense of entitlement--a sense of entitlement that may incline some young people more toward the good life than toward the hard work that, for most of us, makes the good life possible.

Young children learn in a different manner from that of older children and adults, yet we can teach them many things if we adapt our materials and mode of instruction to their level of ability. But we miseducate young children when we assume that their learning abilities are comparable to those of older children and that they can be taught with materials and with the same instructional procedures appropriate to school-age children.

Taking the child's point of view demands good will, time, and effort on the part of parents. The child is the clear beneficiary. Parents who make the effort to understand their children's point of view are likely to treat children fairly and in an age-appropriate manner.
