    A young man went to the local expert(专家) on gems and said he wanted to become a gemologist(珠宝家). The expert turned him down because he feared the youth would not have the patience to learn. The young man asked for a chance. Finally, the expert told the youth, "Be here tomorrow."
    The next morning the expert put a jade(玉) stone in the youth's hand and told him to hold it. The expert then went about his work, cutting, weighing and setting gems. The boy sat quietly and waited.
    The following morning the expert again put the jade stone in the youth's hand and told him to hold it. On the third, fourth and fifth days, the expert asked the young man to do the same thing. On the sixth day, the youth held the jade stone but he could no longer stand(忍受) the silence. "Master, when am I going to learn something?" he asked. "You will learn." the expert said and went about his business.
    Several more days went by and the youth almost lost his patience. But one morning as the master put the stone in the youth's hand, the young man said without looking at his hand, "This is not the same jade stone!" "You have begun to learn." said the master.
    Practice makes perfect. The experience we learned from practice teaches us and develops our abilities. Experience is the best teacher. Even the most successful person had no absolute confidence once. It is experience that gives people confidence. The truth is: if you do the work and gain the experience, you'll have more confidence because you'll actually know what you're doing.
