This. Elon Musk is quoted (?) as saying "If you work 100 hours while others work 40 per week, you can do in 3 months what they do in a year."

If I overwork myself, I quickly get into a negative feedback loop of "never being caught up and satisfied with work." I learned to internalize the idea of keeping myself happy (stable work/life) first, as in the long run this is the most effective situation.
