it’s that If there’s a problem or hassle, it’s usually because of others; and Sartre was right–Hell can be other people.
Relative to others, it has been a long-time practice for me to walk away or detach when others are negative forces of energy or simply toxic. Often relationships ended simply because of the limits and limitations of others and their deep zero growth possibilities. That is, the other person was incapable of making constructive and positive changes often to their own detriment, let alone mine.
Life is short and there are many positive possibilities and personal growth possibilities, often not requiring the presence of another.
In the end, one cannot count on others except one’s dog, one’s closest family (often) and one’s truly close few friends. In that, much value and gratitude for the best playing out of Truth in human relationships.
