All of those amazing things you have accomplished? You did that! Not somebody who coached you or advised you or held your hand as you took the brave steps toward a better you.
That coach, advisor or hand holder? Sure, they were helpful. And maybe even invaluable with regard to your success. But never underestimate what you brought to the table; you with your courage, your never-say-die attitude, your will to do wherever it took.
You are the hero of your story. You battled the forces of fear to earn the victory! Don’t sabotage it and you by giving the glory to someone else.
