Hi - Nice intro post.... I'm at just that stage of looking to quit my job and try and survive off doing what I want to do rather than doing what the system wants me to do.
Scary as hell making the leap! Good to hear it's all working out for you.
NB - I think another key variable on the path to financial freedom is to learn to live with as little possible. If you're interests just include hanging out, working out, gardening, reading, and there's a whole load of other non-consumerist things I could add in, then you really don't need a whole lot to be financially free.
