Don't forget to eat (both in real life and in the game) because it keeps your stamina up and you'll need it.

Slow down the movement of your character from the start by pressing him and sliding down the speed bar. This is important because it will save you the energy and reduce your need for food.

To eat, tap on the backpack and then click the specific food. Many people find this confusing, but all you need to do is tap the fork and knife icon after that.

Like in real life, you should change your clothes often and according to the weather conditions.

When travelling in a cold, wintery environment, you should wear a bandana or something similar, as it will give you additional stamina. You will see the benefit when you realize that there isn't enough food around.

Your priorities should be weapons/tools, food and, of course, quest items. If you don't have enough space for any of these, remove some secondary items.

If you wish to do so, you can steal gathered materials from other players, you just need to act fast and collect them as soon as the player obtains them.
