Vacation is not about having less work. Vacation is about doing something
different than you do usually, on a different schedule and probably with no
big expectations to meet. Helping one's uncle to build a shed can be vacation
to some people. Writing a program one wanted to write for a long time can be
vacation, too. Spending three weeks in one's shop on woodworking can be
a fulfilling vacation as well. So can be going on an international tour or
doing nothing but reading seven different novels one after another.
Getting out of the daily routine, by either laying next to the pool in an all-inclusive hotel or being busy all day building something in the sun, changes your perspective and increases your stress resilience in my experience. Burnout is often the result of one's inability to put tasks aside for a few days.
