Brainstorm your ideas and facts about your life. Before you start writing the autobiography, it is an advisable idea to jot down significant events in your life along with any other facts about yourself that you consider important. Everyone's life has challenges and ups and downs, and these are the elements that make your autobiography stand out.
Organize your ideas in an outline. Once you have narrowed down the list of important facts and events in your life, you need to structure them. A detailed outline provides a plan to follow and will make the writing process easier for you in the long run.
Write your autobiography following your outline. Depending on your schedule and lifestyle, set aside some time for writing every day. You can use the outline as your guide, simply writing whatever comes to mind. Like most writers, you can carry a spiral notebook around with you to jot down any ideas that may come in the course of the day.
Keep yourself motivated and inspired. As a writer, you will often face discouraging moments of frustration and even writer's block. At those times, reminisce about your life. Indulge in letters and photos from the past and look up meaningful passages in your journals. This will help you return to your book with renewed energy and passion.
Finally, edit and proofread your writing. At this point you are nearly done; however, you need to ensure that the final product is worth reading and is free of errors. Distance yourself from your writing and approach it as an objective reader. Keep the most interesting and exciting parts, but eliminate anything that the reader may find repetitive or boring.
