How to we begin to engage with those who are self-destructive?
Trust in yourself. Show them compassion. Don't listen to their poison, take it personally, or let it into your soul or psyche. See them as lost, and gently guide them to their own wealth of self-creativity.
Sometimes, you will get nothing back but the knowledge & feeling of your good deed.
But, wealth does not come from destruction.
Wealth comes from work and creation.
With more creative people, we build wealth in the world, from which we all benefit.
