Competitive - Competitors take bad breaks and use them to drive themselves just that much harder. Quitters take bad breaks and use them as reasons to give up.
Confidence - Confident athletes have a can-do attitude, a belief they can handle whatever comes their way. They almost never fall victim to self-defeating thoughts. Jordan said he went into every game believing he was the best player on the court until someone proved otherwise.
Control - Successful athletes are able to control their emotions and behavior. They focus on what they can control and don't allow things that are out of their control to affect them.
Committed - Mentally tough athletes focus their time and energy on their goals, process, and dreams.

Composure - How an athlete manages their emotions can determine whether they win or lose.
Courage - Only climbers get to the top.
Consistency - Athletes who stick with a schedule do so through good times and bad.
