Virtually everyone, no matter our religion or practices, lives on a different schedule and has different routines for Christmas eve and day than the rest of the year. Especially in the architectural, engineering and construction industry, except in the most exceptional circumstances (true emergency work), this is time off, for family and friends. Business is placed on the back-burner, and that is good, because the break allows us to recharge and revitalize for the New Year.
I use this time of year (when not visiting with family and resting) to take care of some chores and planning tasks that are best handled with some quiet time. We are working on new websites and business expansion models, and these days are ideal for framing and developing the ideas.
Best wishes, and Merry Christmas!
