You already talk to yourself silently whether you know it or not and that's going to dictate your outlook and actions. It's estimated that 800-1,400 words are said per minute during that self-talk. That is 48,000-84,000 words in one hour. That's a lot of words that can either empower you or disempower you. If you're not conscious and careful of what that self-talk is, the default mode is to be negative to be overly critical of yourself. Make it a habit to talk out loud to yourself to uplift you.
