Sometimes when people say "keep your resume up to date" what they actually mean is job change preparation more generally.

Keep your resume up to date; give some thought to what you'd like your next job to be; do that learning/practice/professional development you've been putting off because it wasn't needed for your last job but might be for your next; make sure you're still in touch with your friends at other companies whom you've been meaning to catch up with but you've both been busy; consider whether there are any company perks or equipment you've become reliant on and decide what you'll do if you lose them; and look over your finances to make sure your arrangements reflect your expectations for the future.
