You know that fear in your gut you get when you start to stutter? Change that to aggression! Be bold, be powerful stop being scared and putting yourself down. Harness that "nervousness" and transform it into power. Do you think pro athletes, musicians, politicians don't get nervous before they perform in front of millions of people? They sure do, but they don't let that energy make them feel small and weak. They allow the energy to be there, but use it to their advantage. Do the same thing. Start doing it today and you'll surprise yourself.
