Wake up and eventually snooze a little further for half an hour or something. Now really get up and have a shower. Pay particular attention to the skin between the toes. The whole body must be clean. Open the curtains of the living room (notice in the corner of your eye the piano, don't ignore it). Air the room for at least 15 minutes. Say good morning to the cats and the rabbit and check that they have enough food and fresh water. Have a strong cup of coffee, a toast with a little butter and bitter orangejam. (Roll, if you like to, a small cigarette of shag). Are your hands clean and well groomed, nicely cut fingernails that don't exceed the fingertips ? Take place at your instrument. Have a sip of coffee and light the cigarette. Feel the freedom. Feel it. Feel yourself there sitting on a chair in front of the keys in the Universe. While you are feeling that, start to aim for a perfect fugue, as warming-up, as a starter, as studying and as a performance at the same time (I'm fully aware that this may not be considered very pedagogic, but hey, we are just starting, we have all of the day and all of the night left no ?). Now, strike those notes ! ...

... Whatever sound you will produce can be satisfying, you feel alive (and maybe kicking). You can improve (or not). The piano as a barometer, telling you how you are today.
Never blame the piano.
In short, the first piano-session of the day is for me the most efficient, never brilliant, but often the most satisfying. Is it "comprehensive" ? Not for me, no. I don't get it, the "why ?", the "big picture", I don't get it. Should I ? I don't know. Do you ?
Very kind greetings to you all.
