The journey of the martial artist is a neverending one. There is never a time when you can stop to say that your training is now complete; for if you do, you will be walking off the path of a true martial artist. A black belt is meaningless token for it is not the belt that makes the martial artist; it is simply the goal of perfecting ones martial skill, that makes one a martial artist.
Learning the martial arts is a daily struggle against one's self discipline. There are many false paths for the warrior to deviate on and miss the truth of the martial arts. The truth about martial arts is fighting. It is not about forms, not about strength building exercises or fitness, it is not about breaking boards, or doing fancy acrobatics, or learning hundreds of techniques. It is not about lineage, or which famous masters you have studied under, or how many styes you have studied.
Sometimes we need to do some of the previously mentioned things to reach the goal, but the truth will always be about fighting. When you design a routine for yourself or seek to learn something, always ask, will this really improve my fighting? Be completey and bluntly honest with yourself when you answer the question. I have seen many people focus on just one aspect and they really are walking off the path. Always seek the truth!
The path to the truth is usually the hardest path. It is frought with misteps, misinformation, and misdirection which can easily lead you astray. It is usually the path that we least want to take. Seek the long path; for seldom does one who always seeks the shortest path stay long in the martial arts. Don't look to take long steps for the truth lies in the smallest of steps. When we are content in taking small steps, then no failure ever upsets us.
Seek to improve your fighting skills by working on your weakest points, and doing the things that you usually hate doing, thats when you are probably walking the path. The path of the martial arts is a life long one, in which belts are irrellevant. It is a journey that only you can start, and one which you will travel alone; for no other person is inside your head hearing your fears, doubts, and misgivings.
Don't worry about your rank, everyday just walk the path and seek the truth, and then you will truely be a martial artist.
