I remember wanting to learn martial arts as a child. I watched Karate Kid and checked out some books from the local library. After countless hours of self tutelage, I was still not an expert. In fact, I learned more in the first week of an actual martial arts class than I did in all of those books. We have to put what we study into motion. If not, it is just like a book on a shelf in our minds. The knowledge might be there, but it is useless without action.
