Step "on" something you can step over.
Step "over" something you can step around.
Eject a failed gun cartridge (a "hang fire") before 60 seconds. (Make sure to continue to point firearm in a safe direction.)
Attempt a rapid without scouting.
Approach a bear, wolf or cougar kill without scouting first.
Continue walking with an uncomfortable foot that might indicate a blister forming. (Remove boot and sock to check.)
Jump from rock to rock when crossing or lining a waterway. (Wade, establishing a firm footing.)
Continue working or hiking if over-tired. (That is when accidents happen.)
Get over-dehydrated.
Swear "bad" words. (I use "Aie", or "Aie, aie, aie" if a really bad situation.)
Underestimate the strength of the current above a rapids. (Better to wade and line the canoe farther to be certain.)
Limb a tree with the axe on the near side of your foot.
Leave a campfire burning in winter time. (It may burn into humus and create a bog fire or a forest fire in spring.)
Assume a camp or stove fire is going well. (Do not leave until fire is well established.)
Let a camp or stove fire die too low before adding wood. (The best time to add wood is when the fire is going well.)
Run from a bear, cougar, wolf or dog. (This prompts chase.) Stand tall, arms outstretched, stick or axe in hand if available. Yell for the animal to stop, then talk gently and back slowly away if possible. In the case of a moose, it may be okay to run if there is a safe place to shelter.
Assume an animal is dead.
Blow up an air mattress while chewing gum.
Say no to rain. (Rain is always better than forest fire.)
Rely on an object outside the canoe to hang on to when entering or leaving canoe. (Instead, grab the painter rope that is firmly tethered to a tree or rock.)
Fell an overhanging tree after tent is erected. (Check before putting up tent. Move tent if already up.)
Pour used shortening directly on flames. (Instead pour to the side and then rake some embers into it.)
Continually check the time of day. (This is a city trait. There is no value in checking the time while working, travelling or doing chores ... when there is still a job to finish. If it means a late meal or a late camp, so be it.)
Step in or out of canoe while carrying anything. (The canoe may shift and cause you to trip and fall! Hence my severed shoulder tendon in 2022.) (Place gear in or out of canoe before stepping over gunwale.)
Leave packs and bags open, even a little bit. (Ants, mice, spiders or snakes may enter to seek shelter. I have had hundreds of ants enter packs stored on the ground moving innumerable numbers of pupae and larvae. A mother mouse once moved her family into a pack, or they were born there. Mosquitoes will hide in a pack that is carried into then opened in a tent.)
Give up … ever.
