Absolutely lack of confidence and fear of failure goes hand in hand and is probably one of the most fears we deal with day to day.
Working undercover I see both sides of it.
Younger less experienced agents too hesitant because they are second guessing themselves.... Not so much for fear of injury but fear of making a mistake.
Older experienced agents too overconfident and willing to take too many chances with their safety.
With competition, you"ve never seen a competitor be hesisitant due to lack of confidence and/or fear of failing?
I think I would be more inclined to use a word like anxiety than fear. Then I might be able to say I've seen a competitor be anxious about failure. But fear doesn't fit to my way of thinking.
