Part of the following quote is mentioned in "Akeelah and the Bee", a heart-stirring movie I saw last night:

Our deepest fear is not that we are inadequate. Our deepest fear is that we are powerful beyond measure. It is our light, not our darkness, that frightens us most. We ask ourselves, "Who am I to be brilliant, gorgeous, talented, and famous?" Actually, who are you not to be? You are a child of God. Your playing small does not serve the world. There is nothing enlightened about shrinking so that people won't feel insecure around you. We were born to make manifest the glory of God that is within us. It's not just in some of us; it's in all of us. And when we let our own light shine, we unconsciously give other people permission to do the same. As we are liberated from our own fear, our presence automatically liberates others. - Marianne Williamson

I definitely recommend the movie:

Coming back to the quote:

There are things each of us, in our hearts, knows that we can do better than anyone else. Yet we hold back, out of some inexplicable fear of being great. Are we afraid that if we prove, to everyone else as well as to ourselves, that we are that good, we won't be able to shoulder the responsibilities that come with the knowledge of that power?

From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked. - Luke 12:48 (NIV)

Are we afraid to find out how much we've been entrusted with, for fear that it's more than we would have assigned ourselves, if we'd have had to make that decision? There's a reason though that that's not our decision to make. Our responsibility is simply to do all we can with all we've been given, and if not for ourselves, for the people who observe our actions and are liberated to do the same with their lives. Every one of my heroes has made me want to do and be more. One day, will your children look at you and be inspired by your courage, because you did all you could with all you'd been given?
