I take whatever I can. The Army taught me it is better have and not need than to need and not have. I typically downsize everything as much as I can. My pack includes:
A knife, small flashlight(led), larger flashlight, batts., compass, latex gloves, ziplock bags, TP, 35 mm film case with matches and striker, space blanket, small first aid kit, folding saw, some 550 cord, and a handful of candy and/or other snacks, various scents/scent killer, and my calls. It sounds like a lot, but it all fits into my pack nicely.
