Write even when you don't want to, don't much like what you are writing, and aren't writing particularly well.
I have decided to self publish a book-- What a crazy idea! But what an amazing feeling. One book is all I have at the moment, but already thinking about how to squeak out another one, to bring some resolution to the first. I wrote this little young adult fiction book a very long time ago, and it addresses a timeless issue, or two.
