Pull out the best stories. The story of your entire life would start to get pretty long-winded, so you'll have to make some decisions about what anecdotes you're going to include. Begin drafting your manuscript by writing out the main stories that will be woven together to create a picture of your life. There are a few main topics that most autobiographies cover since readers find them fascinating.
The consequence(s): Ask yourself, What disaster will happen if the goal is not achieved? What is my protagonist afraid will happen if she doesn’t achieve the goal or solve the problem? The consequence is the negative situation or event that will result if the goal is not achieved. The combination of goal and consequence creates the main dramatic tension in your plot. It’s what makes the plot meaningful.
Also, it’s important to know who you’re writing your life story for. Writing for your family and friends is great! But it requires a different perspective than writing for publication. If you’re interested in getting your life story published by a traditional publishing house, then you’ll need a whole different perspective than if you’re self-publishing your memoirs.
