I find that my state of mind is the most important thing, namely, my expectations. There is a time to write and a time to explore. My first draft comes with expectations that I set upon it, but I also reference those expectations within a larger context. Of course, keeping the awesome end in mind is a good thing too: a finished to present to the world, an honest work that represents my unique way of seeing everything with all its pain and glory. So, turning the first draft into a pleasant experience for me, comes with my willingness to make it work for me in the best way possible. But also, there are times when it is just painful because I'm learning a lesson about myself or because I'm stretching myself really hard to get the worthy goal done. In those situations, I really focus hard on why the work matters to me and make sure I soothe myself with breaks, friends and sometimes ranting. It's nice to be able to have someone to complain to without getting advice of any kind. It's just ranting and I need it.
Wish you all well on your projects. I think what we're doing is great.
