How do you see yourself? Are you self associating yourself with greatness? What are the insecurities you know about yourself? Do you question them or agree without protest? Do you often compare yourself to people who you think is better than you if so why? Realize that people around you everywhere is figuring out how to accept them selves. Look into your mirror and do not judge yourself but look beyond the judgment and you'll find who you are meant to be. The best course of action would be to be aware of self criticism. And most importantly be aware how to limit the chatter within your head. Give yourself a fighting chance. Trust your first choice believe in yourself.
