If you don't have a partner? Do you ever dance just to enjoy dancing? Or, is it forever never ending perfecting of individual figures and technique in general, which will never be good enough? No music, no happiness, only worries about making a mistake and looking crappy... What's the point of all that if you never actually dance (other than couple minutes on competition floor a few times per year)? Ok, I am exaggerating a bit, but you get an idea.
