Be so strong that nothing can disturb your peace of mind. Be as enthusiastic about the success of others as you are about your own.
Think only the best, work only for the best, and expect only the best. Be too large for worry, too noble for anger, too strong for fear, and too happy to permit the presence of trouble.
John Morgan Holland 1924 - 1999
