Expecting the best means that you put your whole heart (i.e., the central essence of your personality) into what you want to accomplish. People are defeated in life not because of lack of ability, but for lack of wholeheartedness. They do not wholeheartedly expect to succeed. Their heart isn’t in it, which is to say they themselves are not fully given. Results do not yield themselves to the person who refuses to give himself to the desired results.
A major key to success in this life, to attaining that which you deeply desire, is to be completely released and throw all there is of yourself into your job or any project in which you are engaged. In other words, whatever you are doing, give it all you’ve got.
A famous Canadian athletic coach, Ace Percival, says that most people, athletes as well as non-athletes, are “holdouts,” that is to say, they are always keeping something in reserve. They do not invest themselves 100 percent in competition. Because of that fact, they never achieve the highest of which they are capable.
