I'm an artist so obsessive is part of the job description. My current obsession— bankers, financiers and so forth, and how much I cannot stand them—isn't one I want but I guess obsessions pick you and not so often the other way round. In an alternate persona I've written many quite polite letters to an imaginary bank manager which I post to my blog The Bouncy Banker. This relieves the stress surrounding the lack of money that is most likely the root of the obsession. I've created a Stress Positions poster that has proved quite popular. Some see the images as amusingly (intentional) yogic (not so intentional) but to me they are a close approximation of how I often feel.
