I've had a very spotty work history, and I always breeze over the holes by explaining I'm frugal and I don't need to work fulltime. Now, I haven't accomplished any great thing, but whether it's studying, traveling, doing art or whatever, it's my life and I refuse to be misinterpreted because I didn't need to commit to permanent fulltime work. I saved money, bought houses. Not so hard to do when you don't have children or other major expenses. I'm very responsible. So, in an interview, I reframe the context, emphasizing what's positive to me, telling the story of my version of success. I don't know if that makes sense to you, but it always worked for me.
