It is essential to be constantly aware of what are the limits within which you practice. Injuries in the Dojang most often occur when students fail to pay attention to their instruction or neglect the principles of limits. EVERYTHING has a limit. Another aspect of concentration is related to the power of "Ki" training. Ki training is the state of consciousness that may be characterized as meditation, and a heightened receptivity to learning. "With a calm mind, one is free from hesitation."

"If one’s mind is made up to learn, then there will be success." Nothing can be learned without patience, while endurance is part of the dues one must pay to gain knowledge.

"If one does not practice regularly than do not face the enemy." Perfection of techniques requires deeply ingrained habits, and a mental attitude of thoroughness. The perfection of techniques requires that they become second nature and reflexive. Perfection in the martial arts is like a jewel.

It is merely a rough stone until polished. If it is not polished, no one will ever know its inner beauty. Training is the same.

"Judge the chance and take the opportunity. Take the first opportunity and be quicker than the opponent." Every technique requires speed. There is a counter defense to any known offense.

Therefore techniques must be done with great speed and efficiency.

"The inner force is concealed until released." Perhaps the most difficult aspect of the martial arts master is to learn how to conserve energy and to relax while under stress. Ki cannot be released if the body is stricken with inner tension and fear. Tension is also the greatest consumer of energy.

Even when the body is not in motion, one can exhaust himself simply by being tense. When you are calm, you are free from hesitation, and when you exhale the Ki sinks to the self. These are the essential elements of conservation of energy.

"All things in nature operate according to a rule. Mankind is one with nature."

One of the most essential tests of character is whether the student is humble enough to subordinate his own personal ego to the rules of the Dojang and respect the gravity of his new powers. The martial arts are not a store bought item that you are entitled to because you pay for lessons. The burden is too great, the reflection larger than the individual.

Everyone is expected to meet with boredom, a so called physiological phenomenon in human life. According to statistics, this generally appears within the first three to six months from the commencement of classes. This is the period for learning only the fundamental techniques and power training for the eventual power and skill. Accordingly, physical tiredness together with impatience and doubt with regard to progress cause an overbearing sense of boredom. Nevertheless, from the seventh month physical tiredness is reduced gradually while the power is gained steadily instilling in one the volition to continue. Therefore, the sixth month is definitely a turning point to decide eventual success or failure. One of the ways to overcome boredom is to attend the Dojang regularly and to familiarize yourself with the training aids.

There is a common tendency among the beginners in the course of Tae Kwon Do training to get tired of repeating the same techniques and being curious to go on to new techniques. This is when they begin to lose concentration. They must realize how important it is to force the technique which they are learning until it becomes habit so it may respond automatically to any contingency. However, this does not mean that one should learn only one particular technique while neglecting others. The secret to making one an expert is to learn completely one by one especially the "pattern" and step by step through incessant practice daily even for a short period of time.

1. Practice Suit (Do-buk): Since it is not designed for grasping or protective purposes, but for the psychological aspect, one can easily train in ordinary clothes.
