I recently started doing this too. I tend to always push myself and try to deliver as much as I can, limited by time and energy — it was hard to get rid of this habit, so I tried to create things outside of work to "bound" that time/energy limit. I started with a challenge of reading and summarizing one ML/CS paper per day, which requires a reasonable enough amount of energy and time that I have to make sure to allocate outside of work. It was a catalyst to help me get back into "reclaiming" a portion of my time and mental energy, and I started getting back into side projects. Taking back my time has given me a lot more purpose and meaning, and brings me back to a sense of curiosity and optimism about technology that I haven't had in a while. It's amazing what feeling some ownership can do, and how much better I feel putting my time and effort into things outside of work. Note: initially I tried to "bound my work-related energy" with non-technical goals, like running and mountaineering. It worked to distract me, but I feel like I needed an intellectual bound as well as a physical one.
