Everyone has a story. Do you want to write it down? Where do you start? You don't have to start at the beginning. In fact, to create interest and hook a reader, start with a dramatic moment! One that instantly pops into your mind! Then what? More memories will be triggered. Perhaps you then zig-zag back to a pleasant or emotional moment or a quiet time of growth in your life. Perhaps an outline, even a simple one with a line like I. When I fell out of the highchair. II. Where I was born. III. The moment my parents thought they'd lost me. etc. Alternate between high tension or action and lower tension or action. Non-fiction can be dramatic and factual. Write in active voice, not passive. Remember to be factual, but that doesn't mean you can't illuminate the facts with poetic imagery. Instead of saying "The sunset was colorful." You could write, "The evening clouds wore various shades of blush for their evening out as the sun shone its spotlight on them."
