I enjoy my current job, but it's still a job. I have people to answer to, politics to deal with, work that I dislike that I have to do in order to do the work that I do like, frustrating people who I have to work with sometimes... the usual.
If that just went away, and I could choose what to do with every moment of my time, and associate with who I wanted, and focus on passions rather than work I don't care about... that would be the best.
I took four months off last year and it was absolutely incredible. Even to the point where when I was (very rarely) bored, I even enjoyed being bored. Sure, four months isn't a year, or ten years, or 40 years, but it just felt like the right way to live. In a weird way it actually felt more structured; I actually planned things with friends (or by myself) at particular times, stuck to the things I'd committed to, exercised more, cooked more, and just felt so unhurried and relaxed all the time.
We'll see, I guess.
