Become a farmer within a tight-knit community of some 100 people. Have a couple of cows, chickens, sheep, crops, fruit trees, ... Everybody takes care of each other and we're (mostly) self-sufficient.
Preferably with some good hiking areas and nice vistas nearby.

Like the Amish?

Make it better
Use all indoor farming techniques with ventilation systems in place and solar lights in a high rise

Farm more than you need sell to nearby towns

Generate your own electricity using solar panels

Farm indoors year round so you don’t fry in the sun

Eat drink and be merry
The rest of the baggage of society leave out of it

Create manufacturing network specific to agriculture gradually

Adopt metallurgical and casting procedures so the smallest factor of production necessary to continue agricultural operation is present inside the community

Thrive

Amish life is hard not enjoyable
I know I’m from THE Amish state and see them

Maintain a system of trade and keep all your money in case you have to buy anything you can’t produce

Live life the way it should be lived in a civilized society where everything you need can be produced through ease and technology

Instead of the form of serfdom presently being practiced

Put in place a Swiss style of military service to train everyone and all to augment security and be able to fight

Arm everyone

Remain vigilant of the outside world

Possibly push all money earned into precious metal stores instead of keeping fiat currency

Or keep monetary stores in proportions

Send a few people out on shifts to also work in the standard economy periodically to augment these stores and remind them of why life in host country sucks
