Wakes up, plays piano, eats food at piano, goes to toilet at piano, when tired sleep on piano. When you dream you only dream about piano. When you speak its only ever about piano. Spend 20 years perfecting a single piece and get so overly obsessed over microscopic details that it scares you when you think about it so much that you must rush to a piano and practice for a few more hours to make yourself feel at ease. Wake up in the middle of the night, get frustrated you can't picture in your minds eye how a piece should be played so then you start playing on your piano again..... etc
