I left full time tech work 3 years ago to start farming and overall, my quality of life has increase substantially. (Though I often joke that I can't tell if it's the best-worst decision I've made, or the worst-best decision.) After having spent 15+ years doing software development, I'd encountered a lot of disillusionment along the way and felt that I was always building something ephemeral and that in 9 out of 10 cases, didn't really matter in the bigger picture of life.
The biggest adjustment was the income disparity between the two - we're definitely a lot poorer at the bank (though rich at the table). That's something we've gotten used to though. Many of my hobbies and projects now involve building things on the farm that end up eventually being used to produce something we'll sell.
I do still supplement the slower winter months with the odd telecommute contract, but the plan is to eventually go all in on farming (hopefully by next year).
