The caretaking has to be done. "Somebody's got to be the mommy." Individually, we underestimate this need, and as a society we make inadequate provision for it. Women take up the slack, making the need invisible as we step in to fill it.

Rarely is it possible to study all of the instructions to a game before beginning to play, or to memorize the manual before turning on the computer. The excitement of improvisation lies not only in the risk of being involved but in the new ideas, as heady as the adrenaline of performance, that seems to come from nowhere.

Improvisation and new learning are not private processes; they are shared with others at every age. We are called to join in a dance whose steps must be learned along the way, so it is important to attend and respond. Even in uncertainty, we are responsible for our steps.

Fear is not a good teacher. The lessons of fear are quickly forgotten.

Caring can be learned by all human beings, can be worked into the design of every life, meeting an individual need as well as a pervasive need in society.

Fluidity and discontinuity are central to the reality in which we live.

In many ways, constancy is an illusion. After all, our ancestors were immigrants, many of them moving on every few years; today we are migrants in time. Unless teachers can hold up a model of lifelong learning and adaptation, graduates are likely to find themselves trapped into obsolescence as the world changes around them. Of any stopping place in life, it is good to ask whether it will be a good place from which to go on as well as a good place to remain.
