Fill your mind with the meaningless stimuli of a world preoccupied with meaningless things, and it will not be easy to feel peace in your heart. - Marianne Williamson

What we call consciousness is our ability to perceive stimuli and to file it within the parameters of our personal story. - Steve Maraboli
TV takes away our freedom to have whatever thoughts we want. So do photographs, movies, and the Internet. They provide us with more intellectual stimuli, but they construct a lower, harder ceiling. - Chuck Klosterman
