“If you feel in your mind you can do it, you can do it. You cannot doubt yourself. Doubt is a killer. You just have to know who you are and what you stand for.  You can have a great mentor, a great partner, a great love in your life who gives you confidence and makes you feel great about yourself. And that’s all wonderful, but at the end of the day, if you don’t believe it, all of that means nothing.”
