If you've lost your way in Minecraft, the first thing you should do is check the world map. The world map will show your location as a small blue dot, and it will also indicate the direction you're facing. If you're still lost, it might help to orient yourself by looking at the sun. The sun always rises in the east and sets in the west. So if you're looking for north, find the direction in which the sun is rising; if you're looking for the south, find the direction in which the sun is setting.
