The childhood story. Whether your childhood was happy or traumatic, you should include a few anecdotes that give a picture of who you were and what you experienced at the time. You can tell the story of your childhood by breaking it down into smaller anecdotes that illustrate your personality - your parents' reaction when you brought home a stray dog, the time you climbed out of the window at school and ran away for 3 days, your friendly relationship with a homeless person living in the woods . . . get creative.
If writing skills don’t come naturally to you, these skills can be acquired when you take a course to learn the basic skills of writing. Such course help you by guiding you to choose the style of writing your autobiography that best suits your personality. This style will then create a powerful impact on the reader and their response to your outpourings.
Show, don't tell. Engage your reader by showing them a specific process or scene, rather than narrate directly to them. For example, write a scene that shows the reader how you discovered your mother’s letters from her family in Poland after her death. This will give the reader key information to help move the story forward, without telling them in a long, uneventful passage.
Build tension and suspense. Structure the narrative so that you have a series of stories leading up to the climax of the conflict. If your central conflict is trying to reach the goal of competing in the Olympics for skiing, lead up to it with stories of small successes and plenty of failures. You want your readers to ask, will she make it? Can he do it? What's going to happen next?
