"If you looked at the contents of your mind, would most of your thoughts be positive, optimistic and accepting, or negative, pessimistic and cynical? An appreciable amount of our sense of well-being is tied to what we think, or the content of our thoughts. Do your thoughts suggest calm and contentment, or anger, disappointment and anxiety?"
"What’s on your mind — or what you think — is determined by how you think — or your thinking patterns. And in fact, certain assumptions and cognitive errors can contribute to an experience of depression and leave people feeling more unhappy about their lives, says psychiatrist and cognitive behavioral therapy pioneer David Burns in his book Feeling Good: The New Mood Therapy. These thinking errors may leave one with a poor view of self, no interest in connecting with others, and no desire or energy to pursue goals."
