A martial arts student went to his teacher and said earnestly, "I am devoted
to studying your martial system. How long will it take me to master it." The
teacher's reply was casual, "Ten years." Impatiently, the student answered,"But I want to master it faster than that. I will work very hard. I will
practice everyday, ten or more hours a day if I have to. How long will it take
then?" The teacher thought for a moment, "20 years."
