If you are going it alone in DayZ, the best advice I can give is find out where you are in the world, then use a map to navigate. It's a lot harder than it sounds but towns and villages have signs and if you continually follow a map you will find your way around eventually.
This map in particular is very detailed and vector based so you can zoom in and see every building outline which helps getting your bearings. It also shows ponds, lakes, and wells clearly when you need to refill those water bottles. It doesn't show deer huts though so look on another map for those. They are great loot spots for just about anything rare and the risk/reward isn't as bad as going into a city/military base.
