It starts from 2007 when I become a web developer, one of the holidays I really enjoy is the Christmas period.
One of main reason most of the people are away, not much of work to do, so we will normally clear the leave before Christmas until New Year, so that's like a 2 week holidays.
After I became a freelance developer, I have brought this tradition as well, stop most of my work during this period for the past few years and it's the same as when I work in the corporate world, people just go holidays during this period, you are pretty safe to take leave and chill at home.
All these years have been the same except 1 year I can still remember doing some last minute client job at my brother's place until the very last minute before the party started, which is pretty weird, you don't normally run a campaign during this period.
I would say please try to give yourself a small break at the end of the year, no need to go holidays or travel, just spend some time stay at home, doing something together with the family, spending some time with the kids and plan for the next year.
Enjoy the holiday. Merry Christmas.
