Einstein always played with a group of mischievous (淘气的) kids and didn't study well.
His father was worried about his future and stopped him to do so. But Einstein said others even did worse. "My boy, you can't think like that," his dad said.
"There were two cats playing in the chimney (烟囱). When the two cats climbed out of the chimney, one of the cats had soot (烟灰) on his face, while the other cat's face was clean. Seeing the dirty cat, the clean cat thought its face must be dirty, so it quickly ran to the river and washed its face. The dirty cat saw the clean cat and thought its face was also clean, so it just walked down the street. "
"Einstein, no one can be your 'mirror'. You have to think for yourself. If you just do what everyone else does, you will never learn. "
Hearing this, Einstein decided to pay more attention to his study and less attention to what his friends were doing. This allowed him to be successful.
