Sounds like prison, but the result was interesting. When I was laid off, and decided to take a month before looking. There were a lot of "life housekeeping" tasks that I decided to do. Looking back I'd recommend to anybody looking to change jobs to try your best to take some time between them, it gives you a different perspective on life when you don't have to worry about a job. It's like a short early retirement. I think you would need a minimum of 3 weeks to really realize the effect.

Something else about those tasks they mentioned, this is how I procrastinate. When I'm really disengaged with something I really don't want to do, I end up mopping the floors, doing laundry, or some other mundane task I don't like doing. Only to feel bad about the procrastination later. When you're intentionally taking time away from something that consumes so much of your life like work, priorities rearrange pretty quickly. I stopped drinking as much on weekends, and my sleep schedule adjusted in a way where I was waking up much earlier because I wasn't staying up all night trying to squeeze as much "free time" before work the next day.
