You cannot help another who will not help him or herself.
In the end, all souls must walk their path -- and the reason they are walking a particular path may not be clear to us...or even to them at the level of ordinary human consciousness.
Do what you can to help others, of course. Show love and caring whenever and wherever you can. But do not get caught up in someone else's "story" to the point where you start writing it. Know what I mean?
Love, Your Friend....
