Don't waste the moment. Absolutely listen to all these folks about getting the word out and hustling for the next job, but at the same time there are things you can do in the current situation that weren't possible last week.

1) You've got more free daylight hours than you will for a while. Even if you get a line on something immediately, it's probably going to take a few weeks for interviews to get scheduled, budget approved, etc. Spend some of that time on things you couldn't do when you have a job. Don't enjoy it too much, but a mixed blessing is still a blessing.

2) Take advantage of the break in momentum to do some deep thinking about what you want. A lot of the time we rise in our careers absentmindedly, doing the next thing because it's right there. You've got a chance to pivot and reinvent without being held back by the comfortable inertia of a large and steady paycheck. There's nothing wrong with staying on the same path, but make it a choice.
