לי זה מזכיר קואן ידוע
A student goes to a swordmaster, and prostates himself before him. "How long, Master, will it take me to learn to be a swordmaster like you?" The swordmaster responds, "Ten years." The student pleads with him, "And master, if I work hard toward, and study every day, and practice every night, how long will it take me to become a swordmaster like you?" The swordmaster replies, "Twenty years." Passionate, the student pleads further, "If I work day and night!? If I do nothing but practice and study?! How long, how long then will it take me to become a swordmaster like you??" And the swordmaster replies, "Thirty years." And the student was enlightened.
