If you're burned out now, you're not a good place to be making decisions about what you should do next. Since you've already planned to take at least a 6 month break, don't start thinking about what to do next for at least 3 months. You'll be able to consider what you want from your work with a clearer mind. If you've been working for 20 years nonstop, the idea of a break or not knowing what to do is probably utterly alien to you. Take some time to get comfortable with it. In case my personal experience helps: I worked for a startup for a few years and it was an awful experience, I was totally burned out. I did some interviews immediately after because "I need a job" and it was a terrible experience for both me and my interviewers because I was resentful of everything and everyone. I ended up taking a few months off and realized that I still enjoyed technology, just not the startup and agency environments I'd been in. My career ever since has been focused on non-profit open source projects and it's been great.
