The correct answer is "experience is the best teacher".
Explanation: In "Free From School" by Rahul Alvares, the author tells us of his experience working in Ashok's fish shop after finishing school. He describes everything that he had learned from observation and trial-and-error through hands-on training. Not only did he learn to take care of fish, he learned how to build tanks, transport materials, and even learned how to deposit and withdraw money. The author expresses that his job has taught him more than school ever could.
