If you have been keeping a journal, this will be a great tool when you're ready to sit down and write your life story. Whether you've written down creative, emotional entries or have simply jotted down your daily activities in your journal, it will help to look back and remember times you would forget otherwise. If you haven't been keeping a journal, start now -- even if you're writing your life story currently, you'll benefit from journaling throughout the process and in the future.
Decide how long you want your life story to be. If you want to write about your entire life, practically from beginning to end, chances are your memoir will be pretty long. You can also choose to write about a specific time in your life, or expand a single event into an entire story.
Even though this is your story, you may want to include a lot of information about the people who have played an important role in your life. While your memory may serve you well, you can supplement the information you currently have with interviews. You'll learn a lot about the people in your life and may gain insight into how they perceived certain situations that you were both involved in. This can add color to your story.
At the end of your life story, you'll probably want to include an outlook for the future. Talk about your hopes, aspirations and goals for the years to come. In the future, you can also add an extra chapter to the book to update your readers on your life.
Consider adding photos into your autobiography. These are great when you're describing a moment in your life that you actually have captured in a photo. It will also help your readers to picture the people and places you write about.
