An excerpt from my book Bliss Or Bust: Uplifting Thoughts follows.
Speaking is intention in action. What you talk about demonstrates the direction of your momentum. What you choose to say out loud is revealing. You show where your focus is and where it generally hangs out by the words you put together and release into the world.
Listen to yourself. Use what you say as additional feedback as to where your focus is. Consider, do your words reflect the love side of the scale or the fear side of the scale? Much better to practice silence if you discover that you are demonstrating the fear side of the scale more than you realized.
