To me, burnout is a symptom of always feeling hopelessly behind. My identity as an employee was always in knowing what was going on, where trends headed, new projects, side work, etc. I now have 3 kids and just navigating the whole parent scene takes up the time I would have spent keeping up. It makes me feel like, if I sit down and watch a TV show it was time wasted so I feel guilty about it. That has really had a negative impact on my own enjoyment in programming.
