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.
