Which is tougher to develop: Confidence, Commitment, or Competitiveness?

Came across an article today with some statistics that I found interesting.

While discussing the topic of ‘How to Create Relentless Competitors’ in a workshop with the University of Michigan coaching staff, a question came up about which intangible is hardest to develop: confidence, commitment, or competitiveness?

All three are obviously critical to a team's success, but which of the three takes the most time and effort by a coach to build and enhance?

The Michigan coaches reported the following based on their experience:

49% said CONFIDENCE was the toughest to develop

47% said COMPETITIVENESS was the toughest to develop

4% said COMMITMENT was the toughest to develop

While confidence is very fleeting and fragile, I've found it can be built in a relatively short amount of time for a new player. However, in my experience, I've found that commitment and competitiveness are the hardest to initially instill into a new player.
