Mankind can be a good guide, even a good example – But I wouldn’t go so far as to base your worth on other peoples opinions, or reactions to you -good or bad!
Mankind can really stand to do in about face when it comes to two things:
1) Being more giving to his fellow human being ‐who has little when he has more than he needs;
2) Keeping his judgments of his fellow man in check -given that he himself is so imperfect;
BONUS: Thinking less of himself and more of others, and; THINKING LESS OF HIMSELF AND MORE OF OTHERS.
