A young man once asked Albert Einstein what the secret of success was. The great scientist told him that the secret of success was hard work.
A few days later, the young man asked him the same question again. Einstein was very annoyed.
He did not say anything but wrote a few words on a piece of paper and handed it to the young man. The young man looked at the piece of paper. On it was written:
A = X + Y + Z
"What does this mean?" asked the young man.
"'A' means success," explained the old scientist. "'X' stands for hard work, 'Y' stands for good methods, and 'Z' means that you should stop talking and get down to work."
