Duality, man.

Let go of the concept that life and it's choices are winnable. In any situation, someone is likely to feel more pleased than another. First, ask yourself if life is ever really black and white. No? Then is it really accurate to assume that there is an all win or all lose situation? Additionally, I would offer that it is often the challenging or "bad" times that provide the greatest opportunity for growth. That said, I'd chose whatever seemed to harm the fewest number of people/places/things from my limited perspective, knowing that there is probably alot that I don't/can't see. Then I would have grace on myself and go have a drink with a good friend and play with a puppy to remind me that not all of life is so fraught with moral dilemmas.
