The development of character and mental strength based on Choi Kwang-Do's tenets is considered the most important overall goal in Choi Kwang-Do training along with the attainment of proper technique. Listed below are some helpful aspects concerning the development of this martial art character or spirit.

The true martial artist conducts himself or herself in a polite and unassuming manner, and is never known to be arrogant, disrespectful, or a "showoff". In particular, talented and/or higher ranking students must realize that no matter how skilled they may become, they must always display proper courtesy and respect, and that they are never above being corrected or needing improvement.

By having a humble attitude and by showing proper respect, the good martial arts student shows to his or her seniors and Instructors that he or she is worthy of receiving higher knowledge and that they aren't likely to abuse the skills imparted to them. Furthermore, the good student displays kindness, generosity, patience, and a willingness to share their skills with others.

This mutual trust and courteous interaction between junior and senior, student and Instructor (the junior/senior relationship) is the basis for maintaining a safe and productive learning environment in the Dojang, and for promoting better social relationship in day-to-day life. If this process were likened to a machine, then courtesy and humility could be considered both the fuel and the lubricant that keeps it running smoothly.

Martial artists stand out as always sticking to their word and following through on their important commitments. Honest, yet tactful in his or her dealings with others, the martial artist strives to always influence those around him or her in a positive manner. Self-effacing, the martial artist tries to recognize and correct his or her own personal shortcomings before criticizing others. Reserved in speech, yet dynamic in action, the martial artist always puts "100%" into everything he or she does, letting a "job well done" stand as an example of who and what they are.

In any worthwhile endeavor, whether it is martial arts training, school or job related goals, setbacks, difficulties, and periods of waning interest can invariably be expected. Realizing this, the good martial artist accepts and even welcomes adversity with a spirit of challenge and a positive mental attitude ("Indomitable Spirit"). By applying resourcefulness, analytical thinking, and patient resolve ("Perseverance") to overcome problems, the martial artist strives to turn mistakes into positive learning experiences, and failures into success. Through self-discipline and determination, the martial artist employs self-motivation and industriousness in setting goals and following through with them.
