"We have to abandon the idea that schooling is something restricted to youth. How can it be, in a world where half the things a man knows at 20 are no longer true at 40 - and half the things he knows at 40 hadn't been discovered when he was 20?"

This quote by Arthur C. Clarke speaks with the concept that learning is not something that is restricted to youth. In a world that is constantly altering and developing, it is important to acknowledge that understanding is not static. What we understand at 20 might no longer be true at 40, and what we know at 40 may not have actually been found when we were 20. This quote motivates us to accept lifelong learning and to recognize that understanding is constantly changing and developing. It is necessary to remain available to new ideas and to be willing to find out and adjust to the changing world around us. By doing so, we can ensure that we are constantly as much as date with the most recent information and can remain ahead of the curve.
