I would like to know about this content that there is a source that can find more knowledge?
plenty of sources. even here on the forum.
however, the best way to learn is to play.
everyone does something else, everyone has their own approach to a problem or a situation. my style of living may not suit you (boring/wrong stats), maybe you yourself are simply more talented for option A rather then B. my advice to live in the unreal world may get you killed.
figure out a way to sustain yourself trough the seasons, build yourself a small home, something to keep you warm and dry, ensure a source of food.
then, go experiment, test, try everything out. go fight a njerp, hunt some deer, build a trap fence, lay some loop snares, ANYTHING.
once you know what you can do and how it works, you won't be asking any of us for advice, you'll know the answer.
on a sidenote, you may want to have a mod or 2, being able to make your own linen is a very handy addition i think.
