Love is probably too strong of a word, though it comes close to what I feel in my current job. But at the very least, I like working, like it a lot, and used to think I'd work forever. But over the past few years, I hit serious burn-out and I hated the feeling of getting up every day and trudging off to work and feeling like I had to. I think human beings are notoriously bad at predicting what will make our future selves happy, and we also tend to project our current feelings (good and bad) into the future as if they'll stay that way forever.
For me, the real goal is not to stop working, but "freedom of choice." So I can choose to work full-time until the day I die, or choose to work part-time, or choose to walk away should I ever feel as awful as I did last year. I'm the kind of person that does best with some structure and external accountabilities, so working is good for me. But even if I love my work, I find over time that there are all kinds of things I want to do outside of work, and I want to make room for those.
If I were to predict my trajectory, I think I will ramp down my career at some point. I "sort of" did this by leaving the corporate world nine months ago and going to work for a non-profit, so there was a pretty significant ramp-down of income, but I took a leadership role in the organization, so not a ramp-down of responsibilities. Still, it's been awesome. And starting January 1, I moved to 80% time. And I can see myself wanting to work even more part-time for a number of years, maybe forever.
