“Someone who is in a good mood in the morning might love his wife, his job, and his car. He is probably optimistic about his future and grateful for his past. But by late afternoon, he claims he hates his job, thinks of his wife as a nuisance, thinks his car is a junker, and believes his career is going nowhere. If you ask him about his childhood while he’s in a low mood, he’ll probably tell you it was difficult. He will probably blame his parents for his current plight.”
