If you have the opportunity to see the Film version of The Prophet by Kahlil Gibran. I highly suggest you do. It is absolutely incredible, humble and soul expanding. 

You talk when you cease to be at peace with your thoughts;

and when you can no longer dwell in the solitude of your heart you live in your lips,

and sound is a diversion and a pastime. 

And in as much of your talking, thinking is half murdered.

For thought is a bird of space, that in a cage of words 

may indeed unfold its wings but cannot fly. 

Kahlil Gibran
