The passion of not being in print

Now here's a question and one that affects some us here... If you knew you were never going to be published, at least by a major publisher, would you still write? Would you still be passionate about it?
And if you have been published by a major but never would be again, would your enthusiasm take a knock?

This is but one question that's come out of the World Horror Convention here in Brighton and before I post my reply, what are your feelings in this?
