Feel insecure or boring when you speak? America’s top voice coach, Roger Love, has vocal techniques that will improve your voice. Case in point — Bradley Cooper hired Roger to teach him how to sing, and then he won a Grammy. If you want to learn what Roger’s taught Selena Gomez, Gwen Stefani, and Tony Robbins to speak and sing with confidence, this interview is a must-listen. We are a world of monotone, we need to use more notes. A piano has 88 keys. @RogerLove1 via @MarieForleo
