Project Zomboid

If you mean surviving off the land, the starting location "Riverside" is probably the easiest to start with, if one gets out of town and keeps going North? (Up direction) you'll have an infinite supply of dirty water, which one can also catch fish with a wooden spear, that will need to be cleaned either by fire or, if the electricity is still on, putting in a container and leaving it in the oven or microwave( personally find using a a large pot best for this) for a bit.

Alternatively, you could find one of the rare water wells which supply clean water that way.

You can also use toilet water besides emptying taps with the food you can eat and scavenge can helping with your hydration needs a little, but having a reliable source of water is important.

A more permanent solution, until the devs at least put a better system in, is connecting your water barrels to your sink which "purifies" rain water and supplies one with clean water as long as there is water in your connected barrels.

Wood glue is bad for you - m'kay, better to keep it to repair stuff.

Who knows, maybe when they release version .42 there will be plenty of new use cases with the revamped crafting that is planned to be introduced.
