Bring the bare minimum gear. Less is more.
Build a debris shelter or lean-to from down wood and leaves. Try sleeping in it with a tent nearby, since it will almost certainly leak if it rains. Shingled bark from dead trees is the most waterproof method. Wear insect repellent and check yourself for ticks very thoroughly afterwards.
Get a firesteel and practice spark-based firestarting--cotton balls smeared with Vaseline work great, but try natural materials like cattail seed pod innards ("cattail down"). Once you get good at it, try striking hard steel (like the back of a knife) against rocks to produce a spark.
Read up on how to start a bowdrill fire, and practice this. Bring some paracord or a long spare shoelace.
