"if you really want to learn something, you need to teach it." There is a common belief, one i myself even held too tightly for most of my life that you have to master something befire you can teach it. But thats so limiting because we are ALWATS learning and growing and the science and wisdom is always gaining new layers. So if you want to learn something, read or listen to the classes, then write them. Then teach them. All these layers integrated is how we truly master our skillsets
