Their thoughts should not be your concern
Has it ever occurred to you that most people see you as they see themselves, that the things they say about you are the things they themselves are?
That’s why some smart people came up with the theory that if you want to catch a thief, send another thief to catch him. Think about that for a minute.
What people think about should be none of your business. Even if you find out what their opinion of you is, it cannot change who you are or how you live your life, unless you let it control you by making other people’s thoughts your thoughts.
You really cannot control what other people think about you (whether negative or positive), but you can control how you think about YOU.
Be comfortable in your own skin. Believe in yourself and not in how others see you.
Like someone said, “Be proud of who you are and not ashamed of how someone else sees you”.
