【阅读材料】

There is a story telling of a religious master who is said to be capable of moving mountains. A man came to him asking for a demonstration (证明). The master sat in front of a mountain for a moment, then went to the other side of it and declared the end of the demonstration. All the audiences were greatly puzzled and begged him for an explanation. He said, “There has been a way of moving mountains; what you can do is to go to the mountain if it doesn’t come.”

One of my friends, though with the makings of a merchant, was bent on being a painter. He resigned from office and devoted himself entirely to painting at home. Several years, however, saw no progress in this regard.

A painful retrospection (回顾) brought him to his senses. He made up his mind to take up business in place of painting. It took him only a few years to become a rich businessman. Meanwhile he spent his spare time exchanging experience and skills in painting. His works finally won acclamation by expert painters and were on sale in art gallery and grand hotels. He had his collections published and his dream of becoming a painter came true at last.
