Today’s question by the reader : Alex

How do we know if we should try to help someone or if we should walk away?

I think that there’s no true answer for this. But I take it from another perspective : how far are you willing to go for someone who is lost? How far can you walk away from your path in order to “help” someone who doesn’t want to be helped?
In The Alchemist, I use the metaphor of the sheperd : sometimes we sacrifice the whole flock for a single sheep. Is it worth it?
