@Ben I would urge caution..
I set out for a similar thing 5-6 years ago and it did not go well, I only ended up traumatised and demoralised. I'm sure you are not as idealistically naive as I was - you can still have your ideals but be in touch with reality (which I wasnt really).
Taking responsibility for your own sense of safety and security is a mark of maturity, make sure that you know your limits and what you can do and can actually achieve. Sure you are an unlimited soul, and authenticity is always important in everything you do, but just be aware of your own limitations as a human being in this life, and take care of yourself - you are the only one who will, when it comes down to it. I do think a grounded sense of safety is important for people on the spectrum with challenges with sensory and social things - to conventionally 'make it' in the world, you need to be able to navigate it well.
I also think its awful people stay in a soul sucking jobs or lives. Ive come to accept people do this for survival and might compromise most of their dreams for having one - having a home and family instead of travel, or being a 'starving artist' - or vice versa, and do what they can to at least have part of their souls needs met - I think the only response to that is compassion. These people tend to turn to drinking or some kind of addiction/numbing just to not feel the pain having to do that and just get by as best they can, they carry traumas and their own burdens, like anyone not completely enlightened.
I used to feel frustrated with these people also, so I get it, but I more just feel heart broken for it. Its more tragic and more complicated than being unwilling to change - its the whole structures of the world (like capatalism, meritocracy and ableism, and the lack of value on human life) and where we are as human beings especially our self awareness of our own wounds when it comes to parenting because so much of the same traumatic baggage keeps getting past down generation to generation just in slightly different form. The way we treat the earth - and every creature on it like "The giving tree" (its a childrens book, hopefully you get the reference).
Anyway, I do genuinely hope things go better for you than they did for me. I still believe in change, of course. Is it not possible to stay where you are and still pursue your dreams - if it is manuscripts, cant this be done online with submissions? If your able to pursue travel, thats awesome, but cant you plan for it budget-wise? and have some money put aside if you dont get a job again straight away, or return to the farm once you are done?
