I think the "IF" part from "If I'm comfortable with the worst-case outcome, then I can move without fear and focus my attention on the opportunity" is the most important part.(Assuming I have clearly evaluated the risks) People probably take it for granted that they are comfortable or focus more on avoiding the worst-case outcome than focusing more on the opportunity.
