Any tips on gaining LP?

[sabinati]

you get more lp for crafting higher quality things

Some other ways that work for beginner LP-drillers are making Querns from stones and partly crafting looms (using just the sticks, and then building only with them.

But if you are going for the long run, then yeah, just farm and hunt (try to do bigger things than rabbits).

Level you carpentry and survival to 10.
Make Q10 stone axe and saw.
Chop down trees and make boards.
Make buckets with the boards.

And get killed by the next environmentalist passing through by chance.

If you have access to acre clay, make earthenware platters. You can just dump them on the floor after crafting them. Good source of LP and environmentally friendly! Also faster than clearcutting a forest, methinks.
Of course, playing in any of these methods is extremely boring. If you're still new, it's more fun to just build the things you need and learn new skills as you go along. You'll have plenty of time to grind afterwards.

Just roll a herd of aurochs and you'll be set.

What if they're noobs and can't?

Making objects purely for the sake of LP is a massive waste of natural resources, and is not well appreciated.

My feeling in this game, is it's best to not worry about gathering LP, just go do things... make a camp, make some stuff you can use, gather food, and you'll gain LP naturally.
