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
The evolution of devices All the first antecedents of man's devices were given him by Nature. Every one of his devices is traceable back to something in nature which suggested the first remote and primitive beginnings of its evolution. And every feature in art that man's mind conceived is conceived by a mind that has evolved as a part of nature: that grew out of nature. The evolution of devices is as much a natural process as the evolution of organisms. David Pye, The Nature and Aesthetics of Design The Evolution of Useful Things creativity
