Do the opposite. Give it your best. Turn it into fun. Ask for resounding joy and success. Otherwise, frustration will kill your dreams.
Frustration can change a positive attitude into a negative one.
The worse thing a negative attitude does is wipe out self-discipline, and when that discipline is gone, the results you desire are gone. People get paid very well to handle frustration. The more frustration you can handle, the more you can be paid. Aim to learn how to handle frustration effectively. Success if buried on the other side of frustration.
