Was your aim to succeed as a businessperson? To be the best parent you could be? To amass wealth? To become a musician? To find love or security? Whatever your goal, think of it as the unifying thread that drives your life, shows the failures and complications you overcame, and demonstrates how you ultimately achieved some form of success as the person you are today.
Your life story, or autobiography, should contain the basic framework that any essay should have, with four basic elements. Begin with an introduction that includes a thesis statement, followed by a body containing at least several paragraphs, if not several chapters. To complete the autobiography, you'll need a strong conclusion, all the while crafting an interesting narrative with a theme.
