While you might not remember every detail about a certain event, I guarantee someone who was there does remember. Asking family and friends for ideas or details of a certain situation can give you a completely different perspective of the event or time in your life. That perspective might prove to be invaluable in your writing. Be prepared; once you get a group of family and friends together to reminisce, you will be shocked at how quickly the ideas come and how one idea can spark another and another and another.
You are not the first person who wants to write about his or her life. Many famous writers, artists, politicians, and businessmen create autobiographies to share their wisdom and experience with a wide audience. Find the autobiography that belongs to the author whose personality inspires you and read it in order to get a basic understanding of autobiographical writing.
