Ohhh I will check this, thank you for mentioning the discussion. With dancing it is so easy for me to simply enjoy the process or if necessary to switch to a more controlled/assessing state of mind. While painting this switch does not come easy to me... here I am often more concentrated on the result (although I enjoy the process) I think perhaps dancing is a more ephemeral and with painting you are constantly confronted with the result.
I have a friend who "teaches" painting with the method from Arno Stern who valued the process strongly (over the result). As you said a interesting discussion :-)
