Here are a few ideas for you and other anons wondering what to study/specialize in. This is based on the assumption that the fall of civilization is imminent (rapid return to the dark ages similar to the fall of Rome) and as such we really need to get the fundamentals covered, if we are to survive, grow and compete with unfriendly factions;
We can't rebuild civilization and live in shit-tier, ugly modern buildings that require constant maintenance work. We need visionary builders/architects to create striking, beautiful and useful buildings and create a sense of home, might and grace. Solid stone buildings that fit in with the landscape and nature, will last for centuries and in styles that will become synonymous with our people.
This is incredibly important, you might want to continue on your current path as it's hard to get into law courses so your skills are rare and valuable. If we want to create a more advanced society that won't fall into the traps of our current one, we need redpilled, fair, just and enforceable laws as a backbone.
The benefits of these are obvious, depending on what resources are salvageable from the old civilization after the happenings (race war, nukes, total financial collapse, famines etc) who knows what we might need to build for ourselves. Good engineers will ensure we have technological, energy and military superiority.
Ships, weapons, vehicles, energy generators, mining tools, comms, cranes, running water, lights, hand and power tools… the list of what engineers could provide for us is almost endless.
For obvious reasons
Also for obvious reasons, we need as many branches as possible covered (surgeons, psychiatrists, midwives, paramedics etc)
We may need animals for certain applications, those animals will need looking after.
We'll need a few personal trainer types to help keep our people healthy, strong, fit and ready for anything.
For navigation, mapping and land management.
We'll need libraries to collect as much knowledge as we possibly can. Every scientific discovery, technological blueprint, piece of medical knowledge and historical lesson needs to be accessible, otherwise we'll be in the dark without knowing it about whatever we're missing. We'll need historians to curate those libraries and pass on the history of our people, and the important lessons to be learned from it.
A lot of European (and probably American) Universities offer military societies where you can train part time to be ready to apply for an officer role after your degree. I would advise this over joining the military outright because the university corps will give you training in tactics, leadership and general warfighting without you having to actually go and fight for a cause you don't believe in. Often there are Navy, Army and Air Force divisions which do different specialized training (seamanship, navigation, orienteering, shooting, flying etc) so do whichever appeals to you more, but remember human capability to build and run planes (requires massive infrastructure) might be a thing of the past soon.
Arts are very important for culture, but I might suggest doing arts as a hobby alongside a more practical field of study. Sing, write, paint or sculpt in your free time and if you enjoy it, you'll begin to excel quite quickly.
Subjects to avoid;
As for my contribution, I'm personally studying Horticulture & Plantsmanship with the aim of specializing in growing plants and trees super-efficiently in controlled environments (hydroponics) such as underground or in space.
What should you study, user? Any of these would be useful, so pick one that appeals to you. There's enough diversity among us that we should end up with plenty from each field.
