The hunger [to success] is the same, no matter what it is that you're doing. It's like an unquenchable thirst to learn more, or to feel like you could have done more, and to be brutally honest and self critical, which is very hard to do. It's easy, and human nature is to just blame somebody else. It's very, very hard to self assess.
It is safest to grasp the concept of the postmodern as an attempt to think the present historically in an age that has forgotten how to think historically in the first place.
