As a teenager I myself suffered from anxiety and used to argue, throw my racquet and never understood why I lost all the time. I embarrassed my dad when I played and he tried to make excuses for me. I was having tennis lessons, so my strokes were good, especially my backhand but I was never taught how to handle my temper and to develop mental toughness.
How do I package 35 years worth of coaching into one course? Gradually, by using small steps. That's what I want you to do. As you go through this course I want you to take a brake in between each section. Go and get a soft drink or a coffee. Yeah, lets have some fun.
I don't want you to think about how this won't work, but take everything on board and do everything I say. Wow, sound like a control freak. Perhaps, but I'll be sad if it takes you 5 years to become mentally tough, and I'll be over joyed if you can do it during the length of this course.
Enjoy the ride with me!
P.S. It's like learning a new language, "oh no", but we do one word at a time.
