Congrats, that's AWESOME!
I will share something that I've found. Maybe you'll find it useful.
Sometimes you need a psychological barrier between work and home. It doesn't feel that way during the excitement of a new beginning, but after a few weeks (or even sooner), you can have trouble focusing on BOTH your home life and your work.
Think about building that barrier. I can be something as simple as a closed door or a dress code, or as complicated as putting your office in your garage.
Good luck!
