Write what you love! If you don't love it, who will?
After all, you are your story's mommy. You gave birth to it, you nurture it, feed it, stay up late at night worrying about it. If you think it's boring, well, what will all those non-mommy readers think?
I heard it in, I think, three different workshops and speeches. Of course, I already believe this with all my heart, but sometimes it's nice to have it reaffirmed.
Follow your heart!
