Don't try to be something other than what you are. Don’t listen to that voice. It's distracting you from being you. You will be a horrible version of someone else. You're an incredible version of you. If you are truly you, if you embrace your skills, your authenticity and fully own that - you will bring the best version of yourself, and no one can compete with that. It's your competitive advantage. Build a world around your strengths. People will respond to that - because it's real, and people crave real.
