Deep Practice

I think this is the first time I really experienced true deep practice in awhile. I was practicing the song "Le Festin d'Esope" on the piano, for one a hour, but it all seems condensed into just a few minutes. I was so absolved in it the entire time, and eventually I just had to stop because my head was going into overload. Part of this may be because it's a decently hard song and I haven't played piano in awhile, or not very passionate practice. But this felt good, it sort of relaxed me I suppose. It has refueled my passion for piano.
