When you see your shortcomings, you will not: be self-respecting, discriminate against others, bully others, and bully the weak;
When you see your own shortcomings, you will: have a peaceful mind, learn modestly, and improve your inner world;
Only by seeing your own shortcomings can you become a valuable and meaningful person.
Does what you do make sense for this society? This is the value of a person's existence.
