Despite Christie Rampone's impressive career, the former captain of the U.S. Women's National Soccer Team has struggled with self-doubt and plenty of obstacles along the way.
She told CNBC that she second guessed herself a lot when she was younger.
"I had the ability. I had the awareness, but I just always didn't think that I was good enough," she said, adding that she wishes she could go back and say to her younger self, "You're good enough. Have the confidence and go after it."
Rampone explained that part of being a professional athlete is getting injured and trying to catch up with the rest of the team. Then there's the possibility of not making rosters or travel squads and getting cut from rosters, things Rampone said she had to overcome.
"I had to just keep believing in myself and keep fighting and persevering through that," she said.
