I have just started working on the Intermediate syllabus too. I'm very excited about it and love some of the exercises. I know all the barre exercises and kind of know the pirouettes, allegro and about half of Variation 1, but not yet entirely secure in doing some of it up to speed. That allegro 2! I'm an adult returner rather than a beginner, so I know the vocabulary and technique in theory - now it's a question of getting my aging body actually to do it properly. I have been doing foot and ankle strengthening exercises for a few months and had been intending to start pointe work after Christmas. However I'm probably going to need to get on with it sooner. We've been told that we should be doing every class in soft blocks, so I'm buying some this week and thinking about making a trip to Manchester or somewhere for a pointe shoe fitting. (Can anyone recommend a good shop in the North-West?)
BG, I know that feeling of wanting to be good and feeling frustrated by the reality of the speed of progress. However, look at it positively as a source of determination. Also, have you checked that your shoes really are the right ones for your feet? I think buying your first pair can be particularly difficult as at the point of buying them you don't know how they should feel or whether they're going to work for you, and it can take trying a few different brands/styles before you find the right ones. An expensive business, too!
Good luck.
