Use simple words and phrases: Think from reader’s point of view. Do not imagine that everybody will know what you know. Readers will be fed up if the story narration demands scrambling for a dictionary each time they come across a big word or surfing the net for new topics that you haven’t described at least in brief. Use only simple words and phrases that everyone can understand, and when introducing a new concept or subject, explain it so they know what you’re talking about.
Think honestly about your experiences, too. Don't just focus on the best parts of your memories; think about the details within those times. While Christmas morning may be a magical memory, you might also consider the scene around you. Include details like your mother making breakfast, your father spilling his coffee, someone upset over relatives coming into town, and other small details like that. Understanding the full experience of positives and negatives helps you paint a better picture for the reader and lead to a stronger and more interesting narrative. Learn to tie together all the interesting elements of your life story and craft them into an engaging essay.
Choose something small, but memorable, like a chocolate, a cup of coffee, or a cookie – something indulgent but relatively guilt free. This tells the Unconscious that it’s okay to learn how to write your life story. There’s nothing threatening going on. And soon enough, your Unconscious will let go of its defenses and allow the memories keep flowing.
Create an outline or a graphic organizer of the major topics and ideas you want to cover. For example, you might make a time-order chart -- a chart with event blocks to organize events chronologically. Or, you might draw a cluster web -- a diagram with connected circles -- to divide your autobiography into sections, such as one for relevant background information, one for life-changing events, one for special memories and one for goals and dreams. Focus on reasons why specific events, situations and circumstances were important to you and how they made you feel.
