A
When I was still a student, I found it hard to get back on track with school after the holiday break ended. Fortunately, I could also make up for late homework. But as a working professional, I no longer have that luxury — any delay or mistakes in my work caused by a holiday hangover may end up being costly. The good news is that with a simple strategy in place, it won’t take much effort to return to your normal productivity level.
Plan your post-holiday work schedule even before the holiday begins. This is the primary reason why I easily got back to my regular workload. As soon as the holiday was over, all I had to do was look at the schedule I prepared two weeks earlier to see what I needed to do. Without it, I would have probably spent a day or two regrouping.
I have to admit that it’s wise to work a little during the holidays. If you feel that’s being too much of a killjoy, choose to work on light tasks — perhaps checking your mail or brainstorming. The point is to avoid work being overwhelming after the holidays. It doesn’t mean you’ll get up in the middle of a family gathering and start typing away in your laptop. Make yourself part of the festivities, only get some work done during times when less is happening.
Stick with your normal body clock. Many people feel tired post-holidays because their body clocks have adjusted to a later waking-up time. If this has happened to you, make sure to try and reset your body clock back to suit your ideal sleeping hours before the regular workweek starts.
It’s important to relax. I know some people who actually spend the holidays being completely stressed out preparing gifts and celebrations. The irony is, they don’t end up enjoying their supposed “vacation time” from work. Avoid falling into that trap and catch up on your sleep.
