We bumble through every day. Hundreds of people we don't know pass by us. We have no idea what kind of they are. Can we see the souls of the people? We can see their appearance, not their inwardness. One who is a nullity for you is maybe the treasure for someone. There are some valid quotes, although they sound like a template. Human worth is also measured by what others think of themselves. Life is too short to waste any amount of time wondering what other people think about you. You can change people's minds, not their mode of thought. Allocate time for people who see your soul, not those who are blind to you. You are precious.
