I think I did kind of okay for an explanation on such a complex subject in only 23 words. I guarantee you that a person without all three of those things won’t break an addiction, but also yeah it can’t be any better defined because all three of them are subjective to the person in question. A good work ethic for me is not the same as it is to you, a purpose in life can be anything, and pursuing the goal can have wildly different meaning as well.
