Decide how long you want the biography of Al Gore to be and what you will include. Consider whether you want to write a full book, or focus on a specific part of his life --- such as the impact of his book "An Inconvenient Truth."
Plan your writing schedule in advance. Give yourself a deadline for research, writing a first draft and completing the book, otherwise you might lose sight of the target. Break the project into smaller chunks so you can execute it successfully.
Research as much information as possible. Go to the library and research about Gore's political history, family life and work experiences. Gather more information from journal articles, newspapers and from his website (See Resources) to get a wide understanding of his life.
Make a skeleton structure of the biography. Work out the order you want to write about his life or whether to make each chapter or paragraph thematic. For example, his political career could be one theme for a chapter, while his work as an investor could be another.
Work out what to include and what to leave out. Using too much description will make the biography too monotonous for the reader, so make a list of the most significant events during Gore's life thus far.
Begin writing. Start at the beginning of the biography to avoid confusing yourself. Make sure you keep thorough references to all your resources --- these are vital to the credibility of your work.
Dedicate at least 30 minutes each day to completing the biography. This will focus your attention and ensure that you do not forget how you are progressing and that the chapters flow.
Read over and edit the biography once it is completed. Check that any facts you have listed are true by referring back to your original resource. Make any grammatical or spelling changes needed.
