One of the subtle reasons we do not move on is that we blame ourselves for unhappy endings. Like children whose parents argue, separate, or abandon them, we may lay the blame at our own feet to make sense of what happened. "What is wrong with me?" we ask. "Why did I let this happen?" Perhaps you could have done something to prevent what happened. Perhaps not. Either way, life is a learning curve and our endings are some of the best teachers we will ever have.
Try This: When confronted with an ending, a rejection, or a dead end, contemplate the take-away lesson by asking yourself: "What did I just learn about myself? What did I learn about the way life works? And how will I apply what I learned to the rest of my life?"
