Only from strength Most people think they know what they are good at. They are usually wrong. More often, people know what they are not good at—and even then more people are wrong than right. And yet, a person can perform only from strength. One cannot build performance on weaknesses, let alone on something one cannot do at all. Peter F. Drucker, Managing Oneself strengthweakness
Their wrongness is somehow more immediate In general, a successful design, which Alexander terms a good fit between form and context, can be declared only when we can detect no more [points that conform to the standard against which we judge]. It is "departures from the norm which stand out in our minds, rather than the norm itself. Their wrongness is somehow more immediate than the rightness."
