Definately get your farm!! and definately Do Not Quit Your Job --- not yet.
Do both for at least two years. It'll take you at least two years to really get into the farming aspect, anyway, and in the meantime, you'll have income to help build the buildings, and buy the critters, etc...
If you quit your job (ie- outside stimulation, society, etc...) you will be going nuts in a couple of years. Some folks could maybe handle the sudden change, but most find it a chore at the very least.
The first year you will be on your honeymoon - it will seem like paradise. The second year the newness will start to wear off and you'll begin to notice all the things you've given up to achieve this dream. If you have considered and planned for a very long time, you may have already decided the "give it up" is worth it. But if it is a spur of the moment thing, you may regret a lot.
Plus, did I mention that you're gonna need money?
My story is - hubby and I wanted to get out of the city forever - we finally got our farm, and the first two years have been wonderful, I don't regret a thing. But... it has cost us more than we thought for little things (like moving to a farm when you have no farm equipment, building chicken coops, barns, stalls, fencing, etc...) We expected some cost - just not as much as we ended up with.
We are retired, so no income, except for what we earn on interest on accounts and from the farm itself. If you want the farm to pay it's own way, you need to plan ahead for that. Expect that cost on top of the regular day to day costs.
so, go for it, but look into it a bit closer and don't do everything at once - go slowly. You may end up buying a few horses and find out you simply can't stand how they smell, or the bother involved in their care, etc..., that sort of thing...
and remember... The absolute worst thing to wish upon your enemy is to win the lottery and achieve all their dreams in one fell swoop - it is usually a recipe for failure.
