Many people spend their lives pretending to be someone they're not. The key to being happy is to live your own life, the one that speaks to you. Show the world who you really are and behave as the person you know you are. Share your natural talents and gifts with the world no matter what anyone says. Be the real you and trust your inner compass to guide you down a positive path.
Happiness means being your true self. If you don't follow your inner voice, or try to act like someone else, you'll likely be miserable. The only path to authentic joy in life is to figure out who you really are deep down inside and be that person every day you're on this earth. Otherwise, you're living someone else's life, and that never leads to happiness.
