Same question I asked below, but: how did you play it on your resume? Did you just put "hiking in Europe", etc.? I'd love to do something like this, but I'm fearful what kind of damage it'd have on my resume.
So, when I got back, and decided to go back to work, I was definitely concerned about it.
In my case, one of the side jobs was a small business being run on eBay, so I had that listed. I also said in interviews that I wanted to take a year off to see the world. Once I got the first job after the break, it was never a concern anymore.
Since then, between jobs I've taken a couple months off, and I've never found it to be a problem. Especially when you say, I was burnt out and I needed to refresh myself before I came back to work. Otherwise, I just wouldn't be as productive. Potential managers definitely appreciate that you can take care of yourself.
(Or rather, the kinds of companies you want to work for appreciate that you can take care of yourself to recognize and prevent burnout.)
