n=1 but they help me hit flow states. almost like they provide 'context' before x, helping me to 'prepare' (or be ready?), filter out the noise, focus. similar in group setting - shared context. i suppose could be 'placebo' but would it matter if the result is what i want, and i can't easily attain it other ways? i do feel it is somewhat of a self-fulfilling prophecy - i am essentially practicing something so getting better at it. not enough reason though to 'practice' an alternative, at least for me personally.
