Having done it now for a year, it sounds like you're pretty happy with how it's going. Are you satisfied with what you've achieved? Or is part of the mindset shift that you're just not thinking in those terms any more and are looking only to the day to day?

In my working life, I've only ever taken about a month off at a time, but every time I've taken a longer break like that, I end up ultimately feeling dissatisfied with myself. I go into it with what a I think is a reasonable list of chores/projects that I want to make progress on, but ended up just puttering around— paradoxically, I get a lot more done when I have short bursts of time and have to force myself to bite off a manageable chunk and actually see it through.

I've heard people argue that a few weeks just isn't long enough to trigger productive restlessness, and that's why a sabbatical is more like 6-12 months. But this is what I worry about for myself if I were ever in a position to retire young.
