Trust in your talent.
You didn’t get to where you are by being a phony. You have talent and equally importantly, you have the courage to express that talent. The people who know you and love you can tell you this, but it won’t be real until you tell it to yourself.
“What if I become egotistical?” That’s a choice. You can give your talent to your ego and use it to feel superior to others or you can keep it for yourself and use it to feel grateful instead – grateful that you’ve been given talent and grateful for all the opportunities to share your talent with others. When people receive you, it is a gift and gifts have nothing to do with ego.
Believe in yourself. You have something incredibly valuable to contribute that only can come from you. The world is waiting and will support you in ways you cannot yet imagine.
