Sure, I don't have any formal "winter break" as part of my vacation for my full time job. However, as someone who recently finished grad school I still will find my coming two weeks of vacation far more relaxing than any month long winter break during school.

I only got a BS and MS and yet during my BS I was always stressed about school, even if not working, and during my MS, you bet I was working through "breaks". I'm overjoyed to be able to totally check out mentally.
