Nothing different, Sparklite tinder and vaseline cotton balls are in my pocket tin and pocket carry. What I try to DO, is play the what if game. On a hike or horseback I mentally inventory my surroundings; that insignificant stream I crossed, the summer dried cattails near the rotting tree, the packrat midden. Now in the car I have a sunday newspaper; instant emergency insulation, tinder,splint material, relatively sterile dressing to name a few uses.
