Convincing yourself that your work is the only hobby you need and doing literally nothing else without regard for proper sleep or food for years nonstop is a pretty quick path to burnout. I used to think about nothing but my projects every waking moment, I'd very often skip sleep just to keep working on them and would frequently not eat anything all day because it was too much of a distraction to go buy something from the cafeteria. These days while I still enjoy spending a lot of time working (kinda unavoidable in a PhD tbh), I make sure to leave some time for hobbies unrelated to work, which has improved my health significantly.
