Reddit mentions of 52 Prepper Projects: A Project a Week to Help You Prepare for the Unpredictable

And that's stage 3, I guess: escaping the matrix and becoming free.

You have to master your weaknesses and squeamishness - the desire for comfort and relief from boredom are your greatest enemies. Here, there, everywhere. Suppress it, and nurture your resilience.

Read Stoic philosophy (Boethius and Marcus Aurelius particularly,) - it will help you conquer your fears. Read Thoreau's On Walden Pond (particularly if you're homesteading.) This goes for every scenario and every approach.

For true palaeolithic living, well, I don't believe it's possible as a vegan, sorry. It certainly isn't in colder climes.

If you weren't a vegan, I'd say learn to hunt and fish (by hand: guns are cheating, unless you can make one - and its ammunition - from scratch. Which you can't.) And tbh, the lack of meat is probably going to mean that it is truly impossible to survive entirely off-grid. It's a catastrophic liability in a long-term survival situation (no offence intended,) because you need a lot more calories living wild than you can possibly get from foraged vegetation (especially in the winter, when inconveniently there's a lot less vegetation to forage,) so if you lose the agriculture, you're dead. But any knowledge or practice is better than none.

I have eaten raw animals whole, I have slept in snowdrifts, I have nursed myself through pneumonia in a harsh Welsh winter without antibiotics, tent or sleeping bag when the nights were hitting -12°C (I did go back to winter foraging from bins after that point - it felt like cheating a bit, but hey, if it's good enough for bears.)

I was lucky enough to have a comfortable cave, a well-stocked woodpile and modest larder (enough nuts and jerky, and a supply of dried rosehips.) And I hacked dormant wild garlic bulbs out of the frozen ground when I so ill I couldn't walk more than 6 paces without needing to sit down and catch my breath.

It would kill me for sure now (even without the pneumonia,) - I'm 50, and in solo caveman years that's waaay past life expectancy. But it didn't then.

If you can catch and kill a rabbit with a bootlace, skin and gut it with your teeth, and eat it raw, you will never starve (even when the rabbits run out, there'll be rats. For as long as the atmosphere lasts anyway.) I set myself that, and many other challenges over the years. Squeamishness training.

A large proportion of humanity would literally rather die than resort to such survival. I've never understood that - but then, I'm a survivor.

And when the atmosphere crashes, and humanity (along with all other aerobic life on the planet,) dies in the superstorm-torn Canfield atmosphere I foresee coming down the pike,... well, that's my current prepping project. But I think there aren't many folks who can really pull that one off (and I'm not at all sure even I can.) Or would want to. Life on this planet is about to get a whole lot harder, and it's only because I'm the stubbornest bastard I know that I'm even contemplating it.

Concerning veganism.

I'm not aware of any indigenous tribes who are or ever were vegans. I don't disapprove of veganism - it's your choice, and I can respect that entirely, but it's not natural - it's a modern, "civilised" fad (no offence intended.) We evolved for omnivory. I do massively disapprove of factory farmed meat though. I'll eat it if I have to (largely to keep my wife quiet - bless her though, she will reciprocate by trying my wildlife recipes too, though she's not a big fan of most of it.) I'd always rather hunt or raise my own (and, after a few decades of practice, I can take out a cormorant at 20 yards with a stone if I'm hungry or curious. Surprisingly tasty actually - very like duck. Even my wife was impressed - she certainly preferred it to puffin, which I consider delicious, but she thought was fishy.)

I don't have many sources to suggest I'm afraid - I learnt from pre-internet books (and life-endangeringly reckless personal experimentation,) so long ago I don't even remember them clearly, but Google is your friend, and there are good YouTube videos for a lot of this stuff I know.

http://instructables.com in particular is an invaluable resource.

This book however is a good set of projects that may help to round out your skillsets and give you some inspiration. Basic, but well-structured, useful stuff.

Hope any of that's useful.

Hope the meaty bits weren't too squeamishness-provoking (consider it a useful lesson if they were ;)

Good luck!
