ToesUp,
You put nicely.
If you’re in pain, I trust you agree that a “useful goal” would be to reduce and then eliminate your pain. That would be your own goal. But then, if you saw that others had similar pains, wouldn’t you conclude that another useful goal (of yours) – and assuming that you had a reasonable chance of achieving it – would be to help reduce the similar pains felt by others, to help your fellow humans?
