Also, if you want to improve your interpretation, don't listen to pieces before you learn them. Or, don't listen to more than just the beginning. Try testing to see if your comprehension and knowledge of the score is comparable to the level you are trying to work at.
work out a warm up routine that conditions your hands. if you do this before every practice, and multiple times a day, this could help you build a solid foundation around what you want to learn, if you create these exercises according to technique that is already reliable-make it your fundamental.

and the reason I mention Bach prelude and fugues is because they are so much fun! I am working on 4 p&f(s) right now, in addition to a Rach etude, liszt piece and just finished the 1st movement of the Chopin 1st concerto, over this break (for half of which, I was mostly deaf). Unfortunately, I have about 8 days left before most or all of those pieces are to be mostly solid (minus the concerto, that was for funnies!)...

I...hate...vacation. This was like...opposite of vacation.
Whatever you work on, I strongly suggest working through the WTC, any chance you get. It sounds amazing, it is spiritual. It is the old testament of piano! it will help develop hand independence, which is very important in Chopin. This will help you improve in ornament execution, which...listen to the ornaments in Bach performed by greatest pianists and try to imitate this, after listening to it by ear....
lots of things you could do.
