Positive self-talk influences mood, emotions, and behavior. It is the internal dialogue in our minds that we are often unaware of. Positive self-talk builds confidence and improves performance, while negative self-talk damages them. Using positive words like "I can" and "I will" activates the brain's reward centers and releases feel-good hormones, helping us to achieve our goals. We should observe our self-talk, interrupt any negative patterns, and replace them with empowering statements about our abilities. Maintaining positive thoughts, words, behaviors, values and habits can help us overcome challenges and achieve our destiny.
