Have you ever had a situation or relationship that seemed so right end up not working out? Maybe it was a career opportunity that seemed like the perfect fit, a friendship that appeared to be an instant BFF, or a romantic relationship where you were sure they were the "one?" And then it ended. And you were not only heartbroken, but shocked because it seemed so right and you don't understand what went wrong?
It's so that you can truly see what is so amazingly "right" about you. I'll explain using the example of a romantic relationship (the same explanation applies to any situation you were sure was "it" which unexpectedly didn't go the way you desired).
