Outline what you do at work and see what can be offloaded, dropped, given to someone else.

Return to personal hobbies. Oddly enough, I actually have to carve time out.
Find ways to spend more time outside of your work environment. Bonus if you can take your work with you. Going on a walk while catching up on a work recording, or going to the park and cleaning out your emails, or have a meeting in a coffee shop.
