To complete this goal: Be able to go to a milonga and have fun dancing without having to explain I'm a beginner. Also, look good and graceful doing it.
Why? I used to take ballroom dance classes, my first semester as a graduate student. Argentine tango (and waltz) were my favorite, and I will admit that I have watched a lot of ballroom dance and dance movies. I'm not very good at dancing, but it makes me happy and I want to be better at it.
