I wrote a book of pig jokes when I was a wee little tiny critter, like 4 or 5. I started writing short stories in elementary school - essay responses on tests, English assignments, whatever. I've always been a reader (started at age 3 and haven't looked back) so making my own stories just seemed natural. For me, the part of writing that's the most fun is just spinning worlds up and seeing where they go - with these parameters and these kinds of things going on, what sort of societies develop? How would people relate to one another if (_insert ridiculous concept here_)? What would it do to a person to actually have to deal with the physical reality of this trope, or that crazy situation, or...? That stuff is great fun for me.
