When we are polite to children, we show in the most simple and direct way possible that we value them as people and care about their feelings.

Certainly, young children can begin to practice making letters and numbers and solving problems, but this should be done without workbooks. Young children need to learn initiative, autonomy, industry, and competence before they learn that answers can be right or wrong.

The shift from the perception of the child as innocent to the perception of the child as competent has greatly increased the demands on contemporary children for maturity, for participating in competitive sports, for early academic achievement, and for protecting themselves against adults who might do them harm. While children might be able to cope with any one of those demands taken singly, taken together they often exceed children's adaptive capacity.

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.

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.

Children in the 21st (century) have been transformed from net producers of their own toy and play culture, to net consumers of play culture imposed by adults.
