Identify your audience. To create an effective bio you need to determine who will be reading your bio and what impression you want them to have. The purpose of your bio will help identify the audience. For a job application the audience will be employers, for a speaking engagement the audience will be comprised of people interested in the topic you are speaking on.
There is a good chance that if you haven’t had to write a bio already, that you may have to in the future. A bio is required of many job applicants, it is used on many networking sites, freelancers have to have one for potential clients and if you have a website or blog connected to your business, you should probably have one. Bios provide a concise summary of who a person is and what they do, while at the same time, they allow a bit of personality to come through. There are basically two main functions your bio should perform: 1) establish your credentials and qualifications; 2) create enough interest so the reader will want to know more.
Remember every significant event, unusual experience, or important person in your life. That might take a considerable amount of time, as we think that your life has been interesting enough, and you have many worthy moments. If you want to write about your childhood, you’d better apply to the “experts” – your parents. Perhaps you did something outstanding and awesome when you were a child.
Discuss any special circumstances such as obstacles or challenges you've faced, and how you've dealt with them, recommends Xavier University. This is especially important if your autobiography is for a college or scholarship application. For example, you might write about struggles you faced growing up in a multiracial family or how you've learned to live life to the fullest, despite being a diabetic. Your autobiography should be an honest representation of who you are, so avoid embellishments and exaggerations, suggests author and public speaker David Ford. The goal is to help readers understand how events, hardships and experiences have molded you into the person you are today.
