You may not have had the most interesting childhood in the world, but everyone has had a few memorable experiences. Highlight the best parts when you can. If you live in a big city, for instance, you should realize that many people who grew up in the country have never ridden a subway, walked to school, ridden in a taxi, or walked to a store a few blocks away.
"I was 12 years old when my mother passed away. By the time I was 15, I had become an expert in dodging bill collectors, recycling hand-me-down jeans, and stretching a single meal’s worth of ground beef into two family dinners. Although I was a child when I lost my mother, I was never able to mourn or to let myself become too absorbed in thoughts of personal loss. The fortitude I developed at a young age was the driving force that would see me through many other challenges."
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.
