I believe that resilience is a key characteristic of successful entrepreneurs. Amanda Ripley has some plausible and useful comments on resilience in the passages quoted below.
(p. 91) Resilience is a precious skill. People who have it tend to also have three underlying advantages: a belief that they can influence life events; a tendency to find meaningful purpose in life’s turmoil; and a conviction that they can learn from both positive and negative experiences. These beliefs act as a sort of buffer, cushioning the blow of any given disaster. Dangers seem more manageable to these people, and they perform better as a result. . . .
. . . A healthy, proactive worldview should logically lead to resilience. But it’s the kind of unsatisfying answer that begs another question. If this worldview leads to resilience, well what leads to the worldview?
(p. 92) The answer is not what we might expect. Resilient people aren’t necessarily yoga-practicing Buddhists. One thing that they have in abundance is confidence. As we saw in the chapter on fear, confidence—that comes from realistic rehearsal or even laughter—soothes the more disruptive effects of extreme fear. A few recent studies have found that people who are unrealistically confident tend to fare spectacularly well in disasters. Psychologists call these people “self-enhancers,” but you and I would probably call them arrogant. These are people who think more highly of themselves than other people think of them. They tend to come off as annoying and self-absorbed. In a way, they might be better adapted to crises than they are to real life.
