Socrates when asked the secret to success

The story goes like this:

One day, a student of Socrates eagerly approached him by a river and asked him. "Master, what is the secret to success? In response, Socrates took the student by the hand and led him into the river. As they walked deeper into the water, Socrates suddenly pushed the student's head underwater and held him there for a while. The student struggled, trying to free himself, but Socrates remained firm and did not let go. After a few moments, Socrates finally released the student and allowed him to come up for air. Coughing and gasping, the student asked Socrates why he had done such a thing. In reply, Socrates said, "When you were underwater, what was the one thing you wanted the most?" The student replied, "Air! I wanted air more than anything else." Socrates nodded and said, "When you desire knowledge and success as much as you want air, then you shall find the answer."
