Throughout your day, when you notice that your thoughts have drifted away, come back to where you are. You'll instantly see why you drifted away, whether because you were bored, anxious, dwelling on the past, or anticipating the future.
Deepak ChopraIf you are having the experience of anxiety, your body is making adrenaline and cortisone, if you are having the experience of tranquility, your body starts making valium, if you are having the experience of exhilaration and joy, your body makes interleukins and interferons which are powerful anti-cancer drugs. So, your body is constantly converting your experiences into molecules.
