Well, maybe not a vacation, but stepping out of the office for a few days might be a good idea. I know once in a while I'll get overwhelmed on my project, and I'll start spending days thinking about it day and night, while staring at the mountain of work that needs to be finished. After a few days, I've accomplished absolutely nothing, but I feel burnt out, and mentally exhausted. Going into the office every day and trying to focus on your project isn't a vacation. Take a couple of days off. Don't go into the office, and don't think about work. Go focus on one of your hobbies, go bike riding, take a short road trip, do some work on your house and paint a room, etc.

When I find myself escaping to HN/Reddit and trying to pass the time, I know I need to go offline, and clear my mind.
