It is a fortunate soul who doesn't experience some form of disappointment from time to time. The hope, wish, dream, goal or desire which we wanted didn't happen, for some reason. You or I had looked forward to this with great anticipation and nothing came from it. While we can rehash the details over and over, there is only one way to look at such an experience. You have to catch yourself in mid thought, and reframe the experience. I like the phrase, "Either this ... or something better." Claim that the occurrence which disappointed you is only a stepping stone to a greater good. When ever your mind wants to make this into a full blown drama, remind yourself "Either this ... or something better."
