If you use a Zipp stove or "Swiss Survival Stove", you can get the firebug out of your system and cook at the same time. Smores are even possible!
Cutting trees is useless, green wood won't burn. Almost never have built any fires, except on very cold (far below freezing, how cold is it when a water bottle freezes solid in July?) mornings in the Sierra, and that only in the designated fire ring. That was just to get everyone else out of their sleeping bags and tents.
State parks here in California forbid any sort of wood gathering whatsoever; it must be brought in or purchased. Nat'l forests allow only fallen wood to be gathered.
