Our 5th 'Most Fearless Tweet' Finalist! (PHOTOS)

On May 3, HuffPost Becoming Fearless and Toyota Corolla teamed up to announce Toyota Corolla's Most Fearless Tweet Contest, which will run through August 31, 2012. Nine finalists will be featured on Becoming Fearless and will receive signed copies of Arianna Huffington's book, "On Becoming Fearless." One grand prize winner and a guest will get to meet Arianna in person in Chicago!

We would hereby like to congratulate our fifth fearless finalist, Karla Helbert. May her moving and inspiring tweet -- and those of the other brave and brilliant tweeters featured in this slideshow -- give you a little shot of courage. Or maybe even a big one.

Are you feeling fearless? If so, why not enter to win Toyota Corolla's Most Fearless Tweet Contest yourself? Just follow @HealthyLiving, then tweet about fearlessness in your own life using the hashtag #becomingfearless.
