What I will be do is prepping a new marketing strategy for the New Year as well as reviewing all of my systems and processes that I currently have in place.
I will also continue to do online networking but I will not be doing anything else besides enjoying the break. I used to feel frustrated with the noticiable slow down but now I cherish it.
You could possibly if you don't already have anything in place, come up with a solid marketing plan while it is slow now.
