There are many agents who take a holiday in December and don't look back at their business. They pass it off on another agent in their office or maybe they don't have any new or old business to contend with when away. Not every agent is a top producer.
Some agents are very happy selling a house every now and then and don't feel compelled (like this Sacramento Realtor) to turnover 1 to 2 houses a week. Nothing wrong with no desire to put your pedal to the metal, but I would go stir crazy if I didn't have a million things going on. It's just how I am wired. It makes me happy to sell Sacramento real estate, and I make sure I have a long enough vacation to accomplish both rest and closing more business.
