An old proverb says that even heaven cannot make a diligent worker poor. However, in Taekwon-Do, diligence or intensive training alone does not produce quality techniques. On the contrary, instructions from a false or unqualified instructor would be worse than not being taught at all because unscientific movements not only reduce the power but require a tremendous amount of time to correct. On the other hand, under the proper guidance of a competent instructor, a student who trains earnestly with dedication will learn the true techniques of Taekwon-Do in a comparatively short period of time with less effort.
