My job burnt me out to the point where I was no longer interested in doing anything artistic again. I kind of white washed my walls at home too, they have prints of flowers or whatever but no more "real" art. I think the process of writing my thesis drove me a little nuts, then diving into the self-righteous atmosphere of higher learning and all the narcissistic people who work there helped drive me over the edge.
So I quit everything, making art and being tenure-track both. I'm not as successful or whatever, but I sew pretty quilts and talk long walks and generally think of myself as retired. I know other SAHMs would flame me for implying it's like retirement, but that's where I'm coming from. Maybe because limbo feels like heaven when you used to live in hell.
