Confidence applied properly is the path of genius. You must always be in a state of confidence. And the way you sustain a state of confidence is by testing yourself. Difficult quagmires that may occur; there's always a test. You have to seek them out. You constantly have to test yourself to prepare for these quagmires. That's why I always put myself to the test.
