I need to remind myself of core motivations. Okay, reminder to self follows.
The experience of reading fiction is the experience of entering some one else's dream world for a little while. The act of writing is the act of sharing that dream state with other people. Or even with one's self. I write now so that five years from now, when I have forgotten the act of writing, I can re-enter this dream world and enjoy it for a little while. I don't need to worry about what other people might make of this dream. All I have to worry about is whether I'll enjoy it when I trip over it again.
No psyching myself out any more.
