Eckhart Tolle

 The voice in your head that likes to fret, complain and fantasize is not you, it's only pretending to be you. You can go along with the chararade or you can engage in a more difficult, mature process of recognizing yourself as the awareness behind the voice. In this recognition you awaken from the unconscious identification with your petty self. The voice loses its power and instead of discontentment, a gratitude for the way things are begins to unfold.
