I think there is a danger with young people of being dependent in the sense that they don't acquire any identity or self-image of themselves as thinkers. They just go and look it up or they just chat with someone. In other words, relying on something rather than saying: "Okay, I've got the information, how do I create value from it?"

Vertical thinking is selection by exclusion. One works within a frame of reference and throws out what is not relevant. With lateral thinking one realizes that a pattern cannot be restructured from within itself but only as the result of some outside influence. So one welcomes outside influences for their provocative action. The more irrelevant such influences are the more chance there is of altering the established pattern. To look only for things that are relevant means perpetuating the current pattern.

Unhappiness is best defined as the difference between our talents and our expectations.
