When you can no longer do what you used to do, for whatever reason, it can be tough to move forward. Sometimes it is important to mourn what no longer is, so that you can say goodbye to it and move on. It is particularly hard when you have defined yourself by what you did. Remember this: you are not now, nor have you ever been, what you do. Circumstances may be different than they were before; age, a disease, or an accident may have changed what you can and cannot do. You are the same person you always were. Maybe you can’t play the piano, hike mountains, or do other things you used to do. You are still you. You are not defined by what you do.
