I'm 13 years into my career and I haven't taken more than 5 days off in a row. That's usually a family reunion. I think 4-8 weeks to recharge and reset would be helpful. What's the research say?
Wish I could do that too. But sabbatical is usually reserved for the elite engineers in elite firms.
In my country you get to build your holiday days, so I could totally take a month off if I don't take any other days off this year. Hell, we even have a website to perfectly time it here so you get the most bang-for-your-days. lmao.
I will never comprehend this Silicon Valley mindset. You can also be a 10x engineer while drinking a martini in the balkans.
