One of the great things I have learned on my way to Beijing is the practice of Neuro-Linguistic Programing (NLP). This is a practice of controlling your thoughts, feelings and body to achieve spacific tasks. According to NLP.COM "Neuro-Linguistic Programming (NLP) is a behavioral technology, which simply means that it is a set of guiding principles, attitudes, and techniques about real-life behavior, and not a removed, scientific theorem.
It allows you to change, adopt or eliminate behaviors, as you desire, and gives you the ability to choose your mental, emotional, and physical states of well-being."
I started practicing NLP in January 2008 after reading the following book. My game has improved as a result of the NLP exercises- this is some very cool stuff that has proven to me the impact my mind can have on my sport.
