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. We ask ourselves, who am I to be brilliant, to be 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 is nothing enlightened about shrinking so that others won't feel insecure around you. We are born to make manifest the glory of God within us. And as we let our light shine, we consciously give others permission to do the same. As we are liberated from our fear, our presence automatically liberates others.

The people who have achieved more than you, in any area, are only a half step ahead of you in time.  Bless them and praise their gifts, and bless and praise your own.  The world would be less rich without their contributuions, and it would be less rich without yours.  There's more than room for everyone; in fact, there's a need for everyone.

Life itself is intelligence riding everywhere on chemicals.  We must not make the mistake of thinking the rider and the horse are the same. 
Deepak Chopra - Quantum Healing

Miracle workers learn to keep their own counsel.  Something that's important to know about spiritual wisdom is that, when spoken at the wrong time, in the wrong place, or to the wrong person, the one who speaks sounds more like a fool than a wise one.
