Show, don't tell. Engage your reader by showing them a specific process or scene, rather than narrate directly to them. For example, write a scene that shows the reader how you discovered your mother’s letters from her family in Poland after her death. This will give the reader key information to help move the story forward, without telling them in a long, uneventful passage.
Organize what you've written according to cause and effect and action and reaction. Ordering events according to cause and effect is a natural process. Your car broke down, so you called a tow truck. That's cause and effect. You received a promotion, so you bought a house. Action/reaction happens paragraph by paragraph. He said "No," so you said "Why?" That's action/reaction. She set a wet glass on the table, so you placed a coaster under it, and remembered how your mother used to crochet pretty little coasters and starch them. That's action/reaction.

These two sets illustrate how you should show the entire action and then show the entire reaction. Don't mix the two together in one paragraph. Write your entire book in this way — action and reaction, one complete set after another. If one part of the set is missing, readers will sense an awkwardness. If you're writing an autobiography, or anything else, action/reaction sequences will make your writing lively and natural. As you expand your ideas, write in action/reaction pairs.
Discuss any special circumstances such as obstacles or challenges you've faced, and how you've dealt with them, recommends Xavier University. This is especially important if your autobiography is for a college or scholarship application. For example, you might write about struggles you faced growing up in a multiracial family or how you've learned to live life to the fullest, despite being a diabetic. Your autobiography should be an honest representation of who you are, so avoid embellishments and exaggerations, suggests author and public speaker David Ford. The goal is to help readers understand how events, hardships and experiences have molded you into the person you are today.
