Be yourself, everyone else is taken.
I love this quote!!! LOL. Never heard this one before. But if there is one piece of advice that will cure us all of our insecurities and self-doubt, it is this quote.
Anyone who has left a mark on any sector of society, from the entertainment field to industry and science, is a unique individual. He/she has the courage to be himself/herself without apology. And no one is perfect but in fact our "flaws" shape who we are. Make those flaws work for you.
