I took 2 years off where I made 0 income. Insurance was covered by the government and my healthcare was quite good. I didn't pay taxes because I didn't make any income. Getting back into the workforce happened literally within a single day (this was ~4 years ago when the market was different, not sure the same thing would happen now). I had no trouble switching jobs multiple times afterwards, either—recruiters and interviewers have never seemed to care that I took a break.

I was able to take some much needed time off to focus on personal projects and I'm extremely grateful I was able to do it.

My friends who didn't take time off were able to advance more in their careers, but I think it is a fair trade.
