Don't sleep with socks unless it is very cold. Your feet need to air out or they'll get nasty. They talked about putting the next day's socks and underwear at your feet to keep them warm, I have done that with the entire next day's clothing. Cut weight where you can. Instead of an ax and a hammer, buy one with both on it. If you run out of clothing, hang them out in the sun and air all day to somewhat clean them. Keeping your boots outside is good but be sure to check them for animals before you put them on. Never leave your tent open, you'll get visitors. Always carry duct tape and rope. I prefer paracord, a million uses. Learn how to make lye. Carry at least one decent fixed blade, a folder and a multi tool. If you are back packing, get a good bag with sternum and waist straps and learn how to pack it properly. Red lenses on lights will help to keep your night vision but still allow you to see. MAKE SURE YOU TELL PEOPLE WHERE YOU ARE GOING AND FOR HOW LONG. You might not have cell signal. Carry a first aid kit with bandages, wraps, heat/ice packs, tourniquet, etc A set of work/mechnics gloves will come in handy. Inspect yourself for ticks, rashes and infections. Keep your feet dry and clean. Powder them if needed. Chap stick. Sunscreen. A hat, preferably one that covers your neck too like a boonie hat. Learn how to hunt, clean and cook animals, even if you bring food with you. You might get lost or run out. Know what plants are edible. Many survival books have pictures of plants for you. Can't think of anything else right now but I know I have more.
