Compile documents and items that will help you remember your past such as journals, diaries, old calenders, letters, yearbooks and any boxes of keepsakes you may own. Separating them by year can also be helpful.
Think about your life in terms of topic, such as jobs, places you've lived, spiritual experiences, vacations, relationships and education. This is much easier than trying to remember and write everything chronologically, which can get complicated when you remember key pieces of information long after you've written about a specific time in your life.
Create separate documents about your experiences (computer or notebooks), which enables you to save your work and add details like your feelings and views about a subject or experience or add photos and pictures. Add the names of people involved in your life at that time as well as dates as you remember them.
Make lists of your favorite things, which will help readers get a better understanding of your personality. This can include music, movies, food, items you enjoy collecting, animals, times of year, books and toys.
Talk to your family members and friends about your childhood and times you've shared. Hearing another person recount an experience or time in your lives is helpful, as they can remember things you have forgotten, or help you with the details of an experience you're struggling to remember. They can also potentially provide photos and memorabilia, which can help you remember a certain time or event.
Remember to write about failures or less happy times in your life as well as successes. This makes for a much more interesting read as opposed to a list of only accomplishments and happy or joyful experiences. Once you have compiled enough information by topic, it will be much easier to write your history.
