How do you change what you believe when your experience has convinced you otherwise? By creating a new experience. The best way for you to get that new experience is to change your response to what happens. By the natural law of cause and effect, that new response will create new results, which you will then experience as a new reality. To reach the goal of happiness, act as though the following statement is already true: Everything that happens to me is the best thing that can happen to me.
