Throughout your life, you are writing your autobiography through all that you do. You are in the middle of writing the story of your present and future life. Your current self-image tells the story about yourself until now. Since you are still in the middle of this life story, at any given moment you can speak and act in ways that elevate the story of your life and make it more meaningful. You can choose to do much more good than ever before, become more spiritual, gain wisdom, be kinder, influence others, and refine your character traits. The positive things that you can do now revise the entire picture of your life.
Each minute, hour, day, week, month, and year, you write new sentences, paragraphs, pages, and chapters. The positive choices you make, what you think, say, and do, add self-image-building content to your entire life. Every entry in your autobiography adds to the entire picture. Many entries make just minor additions. At times, an important entry can change the entire picture of where you are now and what direction you are headed.
