In contrast, a "high performance goal orientation" is focused on achievement. As a result, the person is more focused on results than on the learning process. Even if a person "fails", the person with a "high learning orientation" continues to find areas to improve. This person will find that because he or she is able to get past these obstacles, he or she inherently gains confidence in the process. Perhaps there is a way to integrate the two: One can learn from one's mistakes in order to achieve one's goals. The key is the learning process. Phillips, J.M. & Gully, S.M. (1997). Role of goal orientation, ability, need for achievement, and locus of control in the self-efficacy and goal-setting process. Journal of Applied Psychology, 82(5), 792-802.
confidence is all in the head AND you can do work to strengthen that--think of your best tennis stroke and bring that into your consciousness when you are about to hit the ball. works for me. :)
