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.
Norman Vincent PealeIf you think lack you tend to create a condition of lack. Shift your thought pattern to one of abundance and believe that God is now in the process of giving you the abundance you need.
Norman Vincent PealeWhen you get up in the morning, you have two choices - either to be happy or to be unhappy. Just choose to be happy
