Trying to become someone else will always keep you from becoming the person you were created to be. The world does not need another copy. It needs the unique gifts, experiences and perspective that only you can offer. Authenticity builds trust because people connect with what is genuine, not what is manufactured.
The more comfortable you become with who you are, the less energy you spend seeking approval from others. Confidence grows when your character and your actions are aligned. Be yourself with purpose, integrity and consistency. Your greatest influence begins the moment you stop pretending and start living as the person you were created to be.
