Thanks! I know that I don't show the dynamics behind the music, forte seems to be my default state and I'm losing timing if I'll focus too much on it. Not the best feature when playing Frederic "I'm going from pianissimo to fortissimo in three measures and make it seamless" Chopin all things considered ;).
Contrast therapy seems like a good choice, I can actually type :P. And great point about breaks. Ever since I have stopped training sports like a madman I have too much energy and don't really have an instinct to make breaks anyway.
Thanks for feedback and advice! :D
