There's still a month in which you can file an application for the Clarion Writer's Workshop! The deadline is March 1st.
I've told you all what it did for me. It's an experience I wouldn't trade for the world. In addition to what I believe to be the palpable growth in my writing, I've made seventeen friends for life (twenty-three, if you count the instructors) who read and mercilessly critique my work, encourage me when I fail, cheer me when I succeed, and generally make me feel like a member of a tribe.
Sure, it's expensive. But it's a once-in-a-lifetime, game-changing, mind-bending experience. If you want to write seriously, do this. All you have to do is look at the list of writers who are alumni to see the results that can come of it.
In 2010 it's running June 27 to August 7 at UCSD. The instructors will be Delia Sherman, George R.R. Martin, Dale Bailey, Samuel R. Delany, Jeff VanderMeer, and Ann VanderMeer. If you saw that list and your jaw didn't drop, you didn't read carefully enough.
Do it now!
