on Live Write Thrive:

One of the important marketing tools a writer needs is an author bio. This descriptive bit of writing informs readers, in few words, who you are, what you write, and what makes you unique. It’s the marquee announcing your author presence in the world of publishing.

Think about your author bio as your “elevator pitch” that sells you rather than your book.

It may seem odd and uncomfortable penning your own biography, and writing about yourself in third person (which is what you need to do) can makes it feel even weirder.

To compound matters, most of us don’t like to toot our horn and share glowing praise about ourselves. We know how off-putting it is to hear someone brag about themselves and their accomplishments. Yet … we authors need to do just that—with at least modicum of modesty or humility, along with professionalism.

All of this in just a few lines.
