How angsty do you get about your writing, and are you sure you're getting angsty enough? I mean think about it. Have you taken an object or dynamic lately, and filled it forever with some new meaning no one else has seen before, yet somehow fits it perfectly?

Maybe this isn't much of a "resource" but for fun try a google search on terms such as:
—is it dull
—is it awful
—am I pointless

and other highly angst-ridden phrases (I am sure you can generate plenty), and write a story based on the best search results that come up, using topics, word choices, phrases, or anything in sight.

I saw some pretty promising search results. But mostly I hope everyone will join me here in the depths of artistic angst.
