The key to developing personal effectiveness and professional excellence in the business world is being able to apply “discipline” to your life and actions. As S. N. Bremer said, “Self-mastery is the greatest task to which man has ever set his hand to. Self-development, can be achieved only after we resolve to control our self, through the operation and control of our thoughts." All of our emotions, behavior, and abilities, are consistent with the self – image, we hold of ourselves. Your self-image is either your life handicap, or your auto-pilot for success! People with personal effectiveness skills are persistent and resilient in their drive to achieve, and don't let problems get in the way of their success.
