From Nelson Mandella's Inagural Speech

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.
We ask ourselves, "Who am I to be brilliant,
gorgeous, talented and fabulous?
Actually, who are you not to be?
You are a child of God.
Your playing small doesn't serve the world.
There's nothing enlightened about shrinking
so that other people won't feel insecure around you.
We are born to manifest the glory of God that is within us.
It is not just in some of us, it is in everyone.
And as we let our light shine,
we unconciously give other people permission to do the same.

Be big.
