I was lucky enough to have a great geometry teacher when I was in high school. This was back in 1995, and the internet was still a very new thing for the public. So we were still learning the old-fashioned way. But until I had this teacher, I was a very average student. But what he did for me was puzzling in the beginning. Because no other teacher I'd had until this point had ever used such a method. On our first day of class, he did not issue any textbooks. Instead, he issued everyone a sheet of paper with almost 200 terms on it. Our first 4 weeks in his class were to define these terms. But in order to actually pass this assignment, simply defining the terms would not suffice. Yes, we had to regurgitate the definitions. But we also had to go to the front of the classroom and demonstrate our comprehension and also teach it to him. At the end of the 4 weeks, he then issued everyone their textbooks. And as he was doing so, he said to us all, "Now you can all speak the language of mathematics and geometry. Which means that you and I are no longer in need of translation. So we've bridged the gap between teacher and student." He then went on to make a joke that made everyone laugh. Because it was in the language of logic, and we all comprehended it. He said, "If you and I can speak the same language, then we can successfully converse and effectively exchange information." Since his class, I have taken a different approach to how I study. Throughout the years, this method has been useful to me, even to this day. I now would consider myself an autodidact, and learning new things excites me. This teacher and I formed a very strong relationship, almost as a father and a son. He attended my college graduation, and we remained as family all the way until he passed away in 2017. But the main reason I am sharing this story with you is because of a philosophy that he always instilled in me. Which was this, "Don't ever neglect or pass on an opportunity to teach someone something. Especially if they specifically came to you for the knowledge." And what you are doing here is helping others. So I salute you for giving something to humanity instead of taking from it.
