I'm back in the industry at the moment, but I did quit my job a few years back. I hired an allotment, grew a lot of vegetables, taught myself to bake bread and did a few other projects.

How was it? It was just great and it taught me about living on much smaller amounts of money, which is very helpful now that I have children and I work for a charity.

So maybe that's slightly off topic, and more of a career break than quitting the industry, but I'd still recommend it all the same.
