If you are someone who tends to focus on the negative, thinking positively may be a new skill for you. One way to keep a positive attitude about yourself is by writing down and saying several sentences. The sentences should be strong, supportive statements about yourself such as "I am a confident and capable person who can handle challenges." It’s hard to feel defeated when your self-talk is positive. Another technique for reducing stress is positive images. When confronted with a problem, try to imagine the outcome that you want. This technique is used by sport professionals with tremendous success. You too can champion your cause by mentally picturing positive results. Sometimes people are faced with unfortunate circumstances that cannot be changed. In these instances, it may help to think about some of the assets and resources that you have that can support you and help you cope, such as family, friends, skills, education, money and good health.
