Get Your Resume Ready:
Rather than write or update your resume when you have to start a job search, prepare one in advance. Hopefully you've kept your resume up-to-date by adding relevant items as they happened or at least kept a running list of them. That is much easier than trying to remember your accomplishments and the skills you've acquired months or even years earlier. If you didn't unfortunately many people don't—get started immediately. Don't wait for your brain to be in a panic as you set out to find a new job as quickly as you can. It will be even more of a challenge to try to recall information while you're in that state of mind.
