First few videos were of you at the summit. I can see that this is, to start, is motivation to your field of study. With you explaining maybe personals as to why you choose your field and for others, what they could possibly look into to see if they are interested in the same field. Also showing the things youll have to endure, with information. Maybe im wrong, but what you are teaching should be seen. Informative, breaking down sections and even creating sub sections to help people see things on more than just a surface level idea. When your medical career is over, youll make a great professor teaching others, especially with your infecting personality.
