"Discimus ut Serviamus: We learn so that we may serve." I believe that learning is intrinsically a social process and is very goal oriented. If you feel that there is a purpose behind learning a subject, some material or a task, you are more likely to enjoy and feel better about the process of learning. It also helps to know that the task you will be learning about may one day be of use to your or someone you know. It is because of this, and other reasons that I find teaching to be such a refreshing exercise. It gives purpose to learning that has occurred oftentimes many years before the need of the knowledge and satisfies a primal urge to teach our younger generation what we have gained through our experiences. It is almost as if you are creating a legacy with every student that you work with, and by doing so, you also remaster the material you teach. It is ultimately a privilege and a duty of those of us who have more knowledge to pass it on to those of us who come after.
