Strongly concur.

Also make this a yearly habit, so you stay on the ball, know where the market is at, and become comfortable leaving at a moment's notice to avoid this life changing anxiety you might be feeling.

Once you do it regularly, it's no big deal. Companies hire and fire dozens of people a year, it shouldn't be that different for you.

Yes. I would strongly recommending using something like hired. It's dead simple takes maybe 20 mins to sign up. Then once they approve you, you'll get a few inquiries from companies and if you're not interested you lose nothing and if something interesting comes along then you've got your out it should take a few weeks and you should know whether or not you want to stay with SC by then.
