If you want to explore the power of positive affirmations follow these guidelines

1. Personalize your affirmations with with words like "I," "me," and "my." You can't always control circumstances or other people, so make your affirmations about what you can control---yourself. Make your affirmations state your own goals, wants, and values---not someone else's.
2. Some authors say affirmations are best stated in the present tense, because, if affirmations are in future tense ("I will...") your subconscious mind feels no urgency to act NOW. If you feel hypocritical stating affirmations in the present tense (as in "I am slender and healthy") then state your affirmations as a process (as in "Each day I am become more slender and healthier.")
3. Make your affirmations believable and realistic so that you can say them with sincerity. Begin with small, easily achievable goals, and work your way up to bigger accomplishments. "My self control is perfect." is probably more believable as "I have self-control most of the time."
4. State affirmations in the positive. To say "I don't eat fatty foods," only focuses your attention on the behavior you want to avoid. Instead say "I eat nutritious foods."
5. Make affirmations short and easy to remember. Catchy slogans stay with us longer than essays.
6. Repeat your positive affirmations often and positive thinking will become routine.
To maintain positive self-talk, fill your mind with uplifting ideas . Recognize your strengths. Comfort yourself when things go wrong. Let your self-talk be like the soothing, supportive words of a counselor, friend, or mentor. As you improve your self-talk, commit to changing your actions accordingly. Lasting accomplishments come when we change our behaviors as well as our thinking
