In Vivekananda’s school days he knew what he was not going to be in his later years.
He was a most brilliant student in all subjects save and except arithmetic.
One day he was summoned by the headmaster.

Naren’s immediate reply was: “Sir, I am afraid I shall never work in a grocery store!
Therefore, I am not required to be good in arithmetic.”
