The company you keep is up to you, if you surround yourself with people who pull you down and don't see you for who you really are, your potential, your achievements and accomplishments, then I would ask, why?
Comparing yourself to others isn't always helpful as it distracts us from understanding and appreciating what you have achieved in life, your talents, skills, knowledge and experiences, it's what makes you unique, that is what will take you places and help you to stand out from the crowd, your uniqueness.
