Lisa Guerrero chronicles her iconic career—from dealing with harassment as a sports broadcaster to chasing “bad guys” for Inside Edition—and proves that through small, daily acts, bravery is a muscle we can strengthen over time.

I’ve been a cheerleader. A corporate executive. A Barbie Doll. A sportscaster. A soap opera vixen. A sideline reporter. A Playboy cover model. A Diamond Diva. A red-carpet correspondent. An investigative journalist. A disrupter.

I made Dennis Rodman cry. I’ve interviewed three presidents and hundreds of athletes. I costarred in a viral video that has one billion views. I sued the New England Patriots—and won. I tracked down a murderer. I was hit by a car. I butted heads with Barbara Walters. I even played myself in a movie starring Brad Pitt.

During her career in sports broadcasting, Guerrero covered Super Bowls, Worlds Series, NBA Finals, and interviewed sports superstars. From the outside it seemed glamourous, but often she was miserable, told to smile more, argue less, and show a lot of leg and cleavage. Colleagues would joke—sometimes on national TV—that she clinched big interviews because of sexual acts rather than talent. She made a mistake on air during the opening game on Monday Night Football that cost her her sportscasting career... and almost her life.

Fast forward a few years, and Guerrero has achieved phenomenal success as Inside Edition’s Chief Investigative Correspondent. Her stories have led to arrests, changed federal legislation and policies at Fortune 500 companies, and helped shine a light on crime, scams, child abuse, and even cold case murders. And in the last decade alone, she has won over thirty-five national journalism honors and awards.

Today, Guerrero is bombarded with emails and direct messages from people of every generation who all want to know the same thing: “How are you so brave? How can I be brave too?” Women dealing with husbands, friends, in-laws, co-workers, and bosses ask for the courage to request raises, be taken seriously at meetings, and stand up to abusive spouses. Teens and pre-teens ask for advice on dealing with bullies, teachers, and parents. Warrior—filled with the incisive stories of failure, struggles, challenges, perseverance, and finally, success—is her answer.
