Negative thoughts can feed pessimism and create unnecessary stress. You can learn to turn negative thoughts into positive ones. The process is straightforward, although it's challenging, especially at first. Start by following one simple rule: Don't say anything to yourself that you wouldn't say to anyone else. Throughout the day, stop and evaluate what you're thinking. If a negative thought enters your mind, evaluate it rationally and respond with affirmations of what is good about yourself.
