@lfrum I've been there. I'd definitely avoid anger, sadness, and frustration -- I swear potential employers can smell them on you and it spooks them. Cultivate stoicism -- it comes in handy in a lot of areas, sadly enough. (But we don't get sad, we're stoics!)
Tailor resumes to target job listings -- make sure you send a simple 1-2 page PDF, not a Word doc; consider different uses of your skill set; talk to people; and keep your antennae out EVERYWHERE, I got a good job off Craigslist.
