It’s fair to say that people hate the beginning of January almost as much they love the end of December. No more holidays to look forward to, vacation days to relish, company parties to attend, or social gatherings to pencil into our calendars.
I feel your pain—after all the wonderful merriment of last year, we have to go back to the office and do work. Bleh.
I wish I could tell you to coast for a bit, but the reality is that this is the time when your job probably starts to pick up—and so your productivity needs to, too.
