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.
Use simple words and phrases: Think from reader’s point of view. Do not imagine that everybody will know what you know. Readers will be fed up if the story narration demands scrambling for a dictionary each time they come across a big word or surfing the net for new topics that you haven’t described at least in brief. Use only simple words and phrases that everyone can understand, and when introducing a new concept or subject, explain it so they know what you’re talking about.
Create an outline or a graphic organizer of the major topics and ideas you want to cover. For example, you might make a time-order chart -- a chart with event blocks to organize events chronologically. Or, you might draw a cluster web -- a diagram with connected circles -- to divide your autobiography into sections, such as one for relevant background information, one for life-changing events, one for special memories and one for goals and dreams. Focus on reasons why specific events, situations and circumstances were important to you and how they made you feel.
