My mistake (
as a straight male) was not realizing at a younger age how good my pick-up chances were at the ballet.
Seriously, I discovered the ballet about 10 years ago, and go frequently. I am fortunate to live in NYC which gives me ready access to the NYCB (where I have a subscription) and ABT plus many other companies.
And yes, if I am watching an evening performance of three short ballets, sometimes I lose focus by the third. But a DVD is not a true substitute for attendance in person. First, only a very small portion of e.g. Balanchine's work is preserved on video. And the camera changes the ballet. I want to choose what I look at on stage. When Balanchine participated in the Dance in America series in the 1970's he adjusted the dancing for the camera, so that is an exception. I don't know how often that is the case.
