If you white knuckle past the point of burnout, you eventually start getting out of bed again to do hobbies. But only hobbies that feel useful and needed, and only if done feverishly so your brain can't dwell on feeling burnt out and all the fun is gone. Dunno, maybe it's just me ¯\⁠_⁠(⁠ツ⁠)⁠_⁠/⁠¯

Disclaimer: It doesn't go so well for people who wish to remain employed :/
