Affirmations are positive statements that can help you to challenge and overcome self-sabotaging and negative thoughts. When you repeat them often and believe in them, you can start to make positive changes. You can use affirmations in any situation where you'd like to see a positive change take place in your life. These might include times when you want to: Raise your confidence before presentations or important meetings. Control negative feelings such as frustration, anger, or impatience. Improve your self-esteem. Finish projects you've started. Improve your productivity. Overcome a bad habit. Affirmations may be more effective when you pair them with other positive thinking and goal-setting techniques. NOTE: speak your affirmation as if it's already happening. This helps you to believe that the statement is true right now. For instance, "I am well-prepared and well-rehearsed, and I can give a great presentation" would be a great affirmation to use if you feel nervous speaking in front of a group.
