Players and teams that prepare for years for the World Cup or the Olympics begin to feel the nerves a few days/weeks before the actual event. If CAT is giving you that kind of a feeling – congratulations, just shows that you are human! (Even if you are a Champion.)
Remember, just like you, everyone is feeling the nerves. If you can handle them better than others, you will do better than others. The first step towards handling them ofcourse is to realize that it’s ok!
