Learning and teaching often go hand in hand, since both are continuous life experiences. No one is born with complete knowledge and only with an open mind, genuine interest and dedication can one learn and teach at the same time. It is not only from books but also from daily interaction that someone truly grasps the meaning of a lesson. Fear of making a mistake is not a valid reason to stop learning. If that were the case then, we as humans, would have never gotten this far. Trust that you will learn something from each new experience.
