Since I was a kid I heard that there were people who were born with qualities that allowed them to do some trade, that without having studied the techniques to do something, if they seemed to have studied them in the mother's womb while they were growing up. This, because at the time of doing that task they did very well and the results were seen. But there were also people who developed interest in that subject, studied it and became experts in that specific area.
There are also people who, when selecting a university degree, choose to be teachers and study them but in the end they feel they do not like it and they do not teach anyone. Or if they teach they do it without love and the student does not learn.
To be a Teacher you must have the gift of teaching with love!
If we talk about the name of Teacher and teach others, what I mentioned earlier is not the exception. In my particular case, I like to learn a lot of topics, research from the origin to the latest trends and understand why it is done, it is something that I love. There are as many subjects as for example the arts, engineering, agriculture, gastronomy, among other things. My surprise is that when I start talking and learning about a topic, the natural idea always comes out of teaching others about what I have learned and it is not a coincidence that there are always people who are very interested in learning. I have heard people say that God put in me a gift to teach others since I make a complex topic heard and understood very easily.
Although I do not study technically how to teach others I believe that being a Master is something that is born, something that God puts in each person, because I like it a lot and it is very rewarding to see the student overcome the teacher and what you taught served to empower a person of knowledge to do tasks and be a better person. But I think that something more important as a person, is that you could reproduce a knowledge and make someone else perform those tasks that you do, since we live for a short time on this earth and it's worthless to learn something, not teach it and that at the moment of physical death bring knowledge to death with you.
