Autobiographies are not only a privilege of the rich and famous; anyone can write their memoirs and expect at least their close relatives and friends to read their story, provided they have something interesting to write about. Famous authors write about their championship campaigns, their successful movies, an electoral victory or their method of accumulating wealth, but issues such as how you raised your children, how you traveled around the United States on a tricycle or how you avoided financial disaster can also make interesting topics for a specific audience.
Taking the bus, choosing what to eat and searching for a good program on TV are part of everyone's daily routine and not what a reader wants to find on an autobiography. An interesting life story must center on the important events: the success, the failure, the struggle back, the feelings during these events as well as how they forged the author's relationship with those close to her.
An autobiography must not exaggerate about the author's achievements but present every event as it really happened --- at least from his point of view. In addition, writers must not omit details not very flattering for themselves, such as steroid abuse from an athlete or misjudgements by a politician. Autobiographies of larger-than-life personalities can seem more like a work of fiction than an honest account of the author's experiences and can cause to the book --- and subsequently the author --- to lose credibility.
The language style of an autobiography helps the story remain and feel true; for example, a footballer should generally avoid expressing himself in Shakespearean language, and a politician will likely not use overly simplistic expressions. Furthermore, autobiography authors must take their audience into consideration; a father writing his memoirs for his relatives cannot suddenly start adopting an extremely sophisticated tone. Even though the audience will expect an exact account of past events, authors should avoid coarse language in such an autobiography unless they have explicitly warned the readers.
