Can confirm. Have done this for the last several years. Wife stopped working a few years back due to an injury (but no disability or other income for better or worse), so I've been the sole breadwinner the last few years. I've typically been bringing in between $150k and $220k (gross), and we've spent most of the last ... 7-8 years not doing or buying much. Min obligations each month are now around $3000/month (mortgage, utilities, food, insurance), so there's been a bunch of savings.

I can't retire and never have to work again, but I'm slowing down a bit, and spending more time not earning money (gym, reading, travel, etc).

On second though, if I absolutely needed to, we could probably 'retire' tomorrow, and do a bit more belt-tightening - savings/investments would last probably another 10-12 years without any major changes to lifestyle, then could collect social security. But that's... not something I want to do. I like doing most of what I'm doing, and am just being a bit choosier about what I do now.

EDIT: no kids, semi-rural southern US.

EDIT 2: Moderately high, but irregular, income from consulting/contract dev/tech work. Not W2.
