How about taking a look at your weekly or even just your daily route? Driving the exact same route each day and seeing the same buildings can easily make you feel like a postal delivery person. Taking a different route between stops will give a bit of a refreshing change to your scenery, perhaps a new restaurant for lunch, and who knows, you might stumble upon a newly opened shop that would love to see you.
Additionally, take a look at totally changing your daily and weekly routes. If you’ve been calling on the same shop every Monday morning for years it’s sure to feed your "boring Monday syndrome," which is a feeling many people experience at the beginning of the workweek. It's characterized by a lack of motivation, energy, and/or enthusiasm.
As long as you tell your customers in advance that instead of Monday you will be seeing them on Thursday, I guarantee that it will not hurt your revenue, and the change in pace will help you be a bit more enthusiastic.
