You already have good advice here. Summary:
* Avoid popular zones, like around Hub, Necropolis, and Boneyard. Go elsewhere to level.
* Once you're in an encounter, do not stay long. If you're near Hub, exit fast.
* Switch to Real-Time. You can exit must faster.
* Get Outdoorsman up. Use Scout books. At 150 you get fast-travel perks. 175 is max.
* Assume you're being watched, even on the map, because many times you are.
* Test any wild area by entering an empty place on map, and exit. Read text. No red names means no players are there at that time.
* Use Town/World button and preview a town's entry points before entering.
* Build tents next to all towns so you can drop gear before entering.
