Growing up, I did quite a bit of reading on the mental side. My dad, who coached me, had us doing a lot of different types of mental work, like visualization. I read a couple of tennis books that talked about calming your nerves, belief, visualization, relaxing, breathing.

It started with my parents, my dad who taught me growing up, my brother who played as well. I spent a lot of time with him. Then, getting into the pro side, there have been a lot of people who have worked with me along the years.
