Positive and negative thoughts can become self-fulfilling prophecies: What we expect can often come true. Positive thinking, on the other hand, is often associated with positive actions and outcomes. You're drawn to, and you focus on, the positive aspects of a situation. You have hope and faith in yourself and others, and you work and invest hard to prove that your optimism is warranted. You'll enthuse others, and they may well "pitch in" to help you. This makes constructive outcomes all the more likely. When it comes down to it, positive, optimistic people are happier and healthier, and enjoy more success than those who think negatively. The key difference between them is how they think about and interpret the events in their life.
