What is your greatest fear?

"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 most frightens us.
Your playing small does not serve the world.
There is nothing enlightened about shrinking so that other people won't feel insecure around you.
We were all meant to shine, as children do.
It is not just in some of us; it is in everyone.
And as 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."

I heard this quote while watching the movie "Coach Carter" and was totally blown away. I found out that it was actually adapted from the book "A return to love" by Marianne Williamson using my Google Fu. Amazing and inspiring.
