Bathroom Sex Chat and Forcing your creative muse(at 3am in the night)

It was not very chilly on the mid-april spring night when I and Ahmad Kamal were strolling on the College ring road at 3 in the morning. We talked about Freud,Jung,Skinner and other shit. As the angel of sleep is hovering right above my head, I'd like to make a quick note of two points before they fizzle in my dreams:
1)The writing on bathroom walls is done neither for monetary gain nor for fame. Does this qualify it as the purest form of art? What about the masterpieces and classics? In some sense, are they baser than the sex chat in the Daewoo terminal bathrooms?
2)In the creative process, is  discipline and forcing oneself to sit down to design any helpful? Yes says Ahmad Kamal. He says that when, for example, an artist sees a tree, and the muse arrives, he sees beauty, birds, leaves and elation. When he's not inclined to see the tree, at that moment if you force yourself into painting and thinking, you'll notice the negative points, the holes, the dry bark, the asymmetrical pillar. This time he appreciates the other side of the picture. Thus discipline is more than mere clerical work, it generates ideas!

Good luck with your creative processes.
