Financial freedom/liberation. I am pretty happy without much and couldn't handle physically/mentally/and especially spiritually the selling of all hours of the day to do someone else's work. For example, you work a ten hour day and who wants to come home and try and prepare a healthy meal? How will you grow any of your own food? Anyway, I paid my house off a number of years ago and haven't had a credit card for decades either and people are always asking me how I'm making it so well on so little. First step, get out of debt. Yes, I still have to pay property taxes, upkeep and I have an older car (great way to save money is to ditch the car--insurance, gas, maintenance, health costs).
There is a man that I like in this regards, Jakob Lund Fisker. You might enjoy reading his blog or book too?
