Conduct basic research. Depending on your story, you may feel you need to do in-depth research on a certain subject, like air force pilots in WWII or life in a refugee camp in Poland. However, resist doing too much research before you start your first draft. You may get overwhelmed by the amount of information you come across during your research and start to forget your personal take on the facts. Remember that your memoir should focus on your memory of the event, rather than be purely factual or completely accurate.
People usually tend to think that writing all this will be monotonous for them and boring for their potential readers, but you will soon find your life to be unique from anyone else’s as you undertake this task. Add in information like interesting snippets from the lives of your ancestors, their achievements and the popularity of your place of birth. This will inspire readers to gather even more information from other sources.
