It's nice to read a happy ending to a lost in the woods story. 
From the information pieced together from a few articles he knew what to do and kept his wits about him:
He kept a wound from getting infected, conserved his bullets,  used a hole under a large log for shelter,  stuffed the shelter & his clothes with dried grass & leaves for insulation,  started a fire and kept it going,  conserved energy by hunting small game that came within range, found a water supply and stayed near it, etc...
The lesson I take from this is knowing what to do in an emergency and keeping your wits about you can save your life.
