Mental Challenges are for professional athletes too

It's great to see professional athletes recognizing the mental battle that goes on between their ears. In this situation it's tennis pro John Isner. Yet, I can only imagine how he could have been helped throughout his junior, college and young professional career to change some of his failures into successes.

"As a professional athlete, you want to feel so strong and impervious to everything, but that wasn't the case for me and I let him know that," Isner told me in Houston at the U.S. Men's Clay Court Championships last month. "I let him know what I was feeling in the big moments. I let him know sometimes how scared I was."

"I'd find myself seizing up, not freeing up," Isner said. "And just wanting to win so badly that I didn't want to go after it myself, I was a little afraid of that. With how I'm built, it's the absolute wrong thing to do. When other players get nervous and get tight, say, be it a Nadal, a Djokovic, a Murray -- they can rely on their wheels. I can't. I'd just find myself hoping my opponent would miss. I knew what was holding me up was myself."
