When you keep asserting that things are going to work out well, that you can do the job, that you will not have a flat tire, that you will get there on time, by talking up good results you invoke the law of positive effects and good results occur. Things do turn out well.
Norman Vincent PealeThere is a basic law that like attracts like. Negative thinking definitely attracts negative results. Conversely, if a person habitually thinks optimistically and hopefully, his positive thinking sets in motion creative forces - and success instead of eluding him flows toward him.
