I’m pretty fortunate I work in a job with generous vacation, and I use that to take off the week between Christmas and New Years Day. I do this because the holidays involve a lot of interacting with people. Family comes into town, people are out in droves for Christmas shopping and work tries to cram in a whole month of productivity or more before everybody leaves and the new budget year begins. This is fine for a bit, but it wears me out. With a little over a week off for work, I spend several days doing nothing. Rather than being counterproductive, this gives me time to recharge, and somehow helps me prioritize in the new year.
Take some true time off now, and spend it just on you. If you can’t take off the whole week, do take off what you can and spend it alone.
