Your goal orientation plays a driving role in your effectiveness and success as a person, parent, employee, leader, etc. Thus, if you do want to be effective and successful, it is important to question your “why.” What goal orientation do you have? If you have anything but a mastery orientation you are surely putting a limit to how effective and successful you can be.
Moral of the story: How we think matters! It matter to the success of organizations, leaders, teams, and employees.
