The lifestyle I wanted: pretty much as close to zero required work as possible, the ability to do said negligible work from anywhere I feel like parking myself (preferably with good rock climbing), enough money to live comfortably there.
Absolutely achievable, with a couple years of effort (and achieved, by the way.) Try doing that in any other high-paid, high-prestige profession (Doctor, Lawyer, Banker, whatever). Can't do it. Too much doctoring, lawyering, etc. taking up all your time. Sure, you can set up your own practice, staff up, and eventually get the thing running on autopilot. But certainly not in your spare time after work, and definitely not for a few hundred dollars, all in.
So yeah, set your goals right and you'll find you've chosen the one industry where you really can own that coffeeshop.
