That was a bust

I find it rather quite frustrating that I can't seem to find any information on the topic I wanted to research.  It was my plan to write something along the lines of ballet training in Russia and the intensity of doing so.  Yeah...that didn't happen. All I ended up finding was ballet schools that were advertising.  No help.  I've thought about delving deeper into the progression of teaching styles, but once again, I need to be able to pick something very specific because there is far too much information to be able to make my paper concise.
