Today you might be better off walking away from something if it is not working, rather than wasting your energy on it.
You may have to accept today that there are some situations, and maybe someone, that you cant control. Trying to is only going to zap your energy and waste your time. Try to see things from a different perspective and consider that if something is hard and is not working for you, it is not meant to be and you may be better off walking away. Second chances are great, but know when it's over.
