David C. Baker writes in The Business of Expertise:

“After looking at 1,340 examples of successful experts, the only consistent trait was that they were risk-takers. That means that they were wrong a lot — but that they were usually right about the important things.

It also means that they always made decisions. They weren’t so afraid of being wrong that they froze, unable to risk the consequences that come from making a decision and then being responsible for it.”
