Bethany Meilani Hamilton was born on February 8, 1990, in Lihue, Kauai, Hawaii. Raised in a surfing family, along with older brothers Noah and Tim, Bethany learned to surf at the age of 7. She began competitive surfing at age 8, and by age 9 she had got her first sponsorship(赞助) .
In October 2003, after having placed 3rd in the Open Women's Division earlier that year, Bethany's life changed forever. Bethany went out to surf at Tunnels Beach in Ha'ena with her best friend, Alana Blanchard, and Blanchard's father and brother. While lying on her board, Bethany suddenly felt huge pressure on her left arm and was pulled back and forth for a few seconds. Feeling no pain at first, she noticed the water around her had turned red, and her shocked friend first realized that she was attacked by a shark. Hamilton lost her left arm just below the shoulder.
As she recovered, she made two promises to herself. The first was that she would not moan(抱怨) about her terrible accident and the second was that she would get back on the surfboard. After only 26 days, she was surfing again! She is now one of the top 50 female surfers in the world. She also won first prize in the Explorer Women's Division of the NSSA National Championships.
Bethany's story has been turned into many books, including a few written by herself. She has appeared on many TV shows, magazine articles and in 2004 was named the Best Comeback Athlete and also received the Courage Teen Choice Award.
The last two books written by Bethany were based around the theme of being unstoppable. One of her books is named Be Unstoppable: The Art of Never Giving Upand has guided readers to be brave, enjoy life and never give up.
