The Mashgiach Rav Dov Yaffe tells a story about a father who wanted to pull his son out of Yeshiva. In a very innocent and honest way the father told the Rosh Yeshiva that if the Rosh Yeshiva truly believes that his son will become a big Rosh Yeshiva one day he will gladly let him stay in learning and support him. However if not then he should leave Yeshiva and come to work.
The Rosh Yeshiva considered the concept and posed the following to the father. He said, I accept your thinking but why don't we turn the tables. If you are convinced that your son will become the next Reichmann, then by all means take him to work. But if not, you may as well let him stay here where he can learn Torah.
