Try this: put your startup points into getting 3 str 2 s.tyr. Make an iron club (hit the not-gargantuan boulders, scrap the resulting iron ore for iron, drop the nitrate and lead, you'll be mining that by the bucketload later). Loot unlocked houses only for enough cloth to make a bandana and 10 bandages, after that, loot only kitchen, bathrooms, laundry for glass jars and maybe some clothing. Don't bother hanging around and don't expect to find anything worthwhile in places that are easy to get in to, for good odds (which equals no wasted time, time is not money in this game, time is life) loot that's worth anything you have to go scarier places. When you're traveling, run down the roadside not the road, that way you get many more nests easy.
Wolves and boars, put an arrow or two in them if it's easy, but when they're running towards you wait your moment and powerclub them in the face once, that'll stun them long enough to get a regular hit in and kill them. If you've got a pack after you find a way to string them out or it's over for you if you can't run away. Dodging around trees helps.
Fighting at night's not too bad with bright moonlight or failing that torches, put enough distance between you and the zeds to drop a block or pole or frame and attach a torch, now you can see what you're fighting. I leave flagstone poles in the nearby woods so I can chop at night, it's peaceful. Mostly.
With just those startup points you can take out shotgun or working stiff basically first thing, no luck required, just watch your back. Luck into the northern Navezgane spawn near shotgun you can have a forge by noon on day 1, and with any luck on the hunting (for animal fat, for torches, you don't want to be defending in the dark) head south day 3 all loaded up on forged iron, iron arrowheads, nails, the works. S.Tyr 2 enables all of this, somebody's going to have to do a lot of mining and chopping and bashing, and that somebody's going to need S.Tyr.
