Yes, you have to be precisely honest and quite revealing and candid to write a successful autobiography. And obviously, you need to describe some hardships of your life to show how you coped with that or how it influenced you. However, we strongly advise you to describe the thing that you feel rather calm about when writing. For example, you are writing about other students picking and making fun of you at high school. If you still feel like wanting to kill them all, it would be better to avoid this topic or mention it slightly. Why so? Because your feelings will leak into the writing and make your reader feel subconsciously uncomfortable.
Capture the spirit of the times. How was your story shaped by the moment in history in which it took place? What wars influenced your politics? What cultural events inspired you? Be sure to include a few important dates so readers can understand the sequencing of the events you are describing. Discussing what happened in the world at large during your lifetime is a good way to make your story more relevant and interesting to those reading it.
If the purpose of your autobiography is to pass on your story to your heirs, consider including memorabilia (e.g. pictures, heirlooms, medals, mementos, letters, etc.) and putting your story in a scrapbook format. Of course, you may not be able to copy the memorabilia that accompanies your autobiography, so you still have to think about what you intend to do with your original work and other items, such as medals or bulky heirlooms.
Review your outline again and imagine that is is a web becoming ever more intricate. Every spider web begins with a single supporting thread that anchors all others. Then the spider lays key connecting threads, to which it attaches many, many smaller lines. Watch an animated video of a web being built. Your initial scenes of obstacles and failure make up the supporting threads to which all others in your story web connect.
It might be tempting to start your story with "I was born in Dayton, Ohio...," but that is not really where your story begins. It's better to start with an experience. You may wish to start with something like why you were born where you were and how your family's experience led to your birth. If your narrative centers more around a pivotal moment in your life, give the reader a glimpse into that moment. Think about how your favorite movie or novel begins, and look for inspiration from other stories when thinking about how to start your own.
According to the fascinating field of “narrative psychology,” the stories we tell about ourselves are the key to our well-being. If you’ve interpreted the events of your life to mean that you’re unlucky or unwise, it’s hard to look optimistically at the future. Conversely, if you acknowledge that you’ve made mistakes and faced difficulties but seek (or have already glimpsed) redemption, you’ll feel a much greater sense of agency over your life.
Develop a central theme, main idea or thesis that clearly explains the purpose behind your autobiography. For example, your theme might be about how you overcame obstacles to become a stronger person, or it might explain why a particular passion -- such as mountain climbing or rescuing animals -- is so important to you. Back your theme with details and background information about your life experiences. For example, you might explain that your dad is in the military, so you've had to learn how to adapt quickly to new schools and unfamiliar environments. Or, you might discuss what it was like growing up in a poor, single-parent home, but how your family was always willing to take in injured or stray pets.
