About learning Gustavo says this:
But the real point is: if you take written notes instead of just making a video of yourself, it's true that you may never look at the notes again either. But the ACT of making the notes will start to change the way you think about your tango. You will find a way to analyze and explain what you are doing to yourself in symbolic terms. These symbols will become valuable tools for you to analyze the tango you do and the tango you see others do, and will remain at your disposal when you are improvising the social dance. So the act of writing notes about your lessons WILL make you a better dancer, much more than the act of operating your camera.
