Just to add a little more perspective, the opposite of a mastery orientation to learning is called a 'performance orientation'. People with a performance orientation are more concerned with looking good rather than becoming good. They worry more about how they are being judged by others rather than acquiring knowledge and developing skills. They tend to seek out flattering praise rather than accurate feedback and view teachers as critics rather than as valuable resources.

People with a performance orientation tend to believe that performance depends more on natural ability and luck than hard work. Consequently, they are more likely to give up if they don't achieve quick success ("I'm just not cut out for this.") and are easily tempted to look for shortcuts and cheat to achieve their goals.

Studies have shown that the best predictor of learning orientation is tolerance for frustration. People who get frustrated easily and more severely are prone to develop a performance orientation and have difficulty with a mastery approach.

Maybe some people need to chill and have a couple of brews before they play or practice rather than after!
