Yes, I have a few actually.
1) When I get to a certain point in a piece with has, say, 6 sharps in (ahem, *ravel-sonatine*)... I am so afraid of reading it that I just don't bother, and I do it by ear instead. I don't think I can read music, thinking about it. At least, not very well.
2) I bang my piano lid shut when I get in a temper. Even worse, I deliberately shut it on my fingers, and then I can't remove them. So I stand there with my fingers trapped for however long it takes for someone to take pity on me and pull them out. Or I raise the lid with my forehead. This is more arduous though. It requires
effort.3) I used to cease to breathe whilst playing the piano. Now I do deep-breathing.
4) I chat with my mother whilst playing the piano. It doesn't get my full attention.
5) My big poster of Chopin distracts me. I find myself playing Chopin far too much. They are RATIONING me.
6) And so I scream a lot.
7) Whilst playing.

Mozart, not Chopin.... And Ravel
9) And I drink whilst playing. I accidentally spilled some in the strings once.
p.s. I also learn everything by sight-reading. That statement may
appear to contradict no.1, but it doesn't actually.
