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.”
