I don't mean to be negative, but things become boring fast when you have no hobbies and interests outside of work. You were likely programmed to do work -- so much that it became your only hobby.
The sad thing is - especially in software/tech - it's so competitive these days, if you don't "live to work", you won't work enough to live..
As a 30+ year software dev, the expectations / requirements are definitely more challenging than when I started. Mind you, the tools are also somewhat better, but there's this feeling of needing to be always-on that's hard to shake.
And the whole "take as many days as you need" fake-unlimited-vacation thing, where people end up taking less vacation days than before because it feels "wrong" to actually take 4-5 weeks vacation in a year when others aren't taking as much. At my previous employer, when I joined, it was start at 18 vacation days per year, add one for every year at the company up to 28 - and you could bank up to ~35 before you lost days. At least you felt "entitled" to take those days. Then, they switched to "flexible PTO" and I'm sure overall, people took less days vacation. My current employer is "flexible" and I feel anxious taking 4 weeks throughout the year.
