Be revealing. You don't have to be explicit, but it's important to reveal truths about yourself and your life in an autobiography. Don't let the book become a list of your accomplishments, with all the negative material carefully kept under the rug. Present yourself as a whole person, sharing talents and flaws alike, and your readers will be able to identify with you and hopefully root for you as they make their way through your story.

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?
If you are not sure that your whole life path is worth attention, then a memoir is your best choice. It is focused on one particular event, relationship, place, or period of your life that has influenced your personality a lot. Don’t be afraid to express your personal feelings and ideas in your memoir, as it shouldn’t be simply a brief list of facts, but the reflection of your inner world.
Stick to informal language, unless it’s absolutely necessary to use formal terms. Instead of “utilize” you can just put “use”. Focus on simple language, with one or two syllable words. The only time you should be using higher level language is if you are using scientific terms or describing a technical process. Even then, you should be writing for the average reader.
