Step 1: Knife
Knives have multiple uses. Anywhere from cutting things to stabbing things. A knife will make everything easier.
Step 2: Water
It's pretty self explanatory. You can only live 3 days without it. Bring some bottles and maybe a filter as well.
Step 3: Food
Same as water you can't live without it. You can live up to 3 weeks without food but after a few days you'll start to go insane and lose your concentration.
Step 4: Fire
Whether for warmth or cooking fire can keep you alive. Bring water proof matches and other necessities for starting fires
Step 5: Bow And Arrows
Bows will be great for killing animals for food. They can also be used as a source of protection. One arrow can last for years
Step 6: Paracord
Para cord can be used for just about everything. make a hammock or make a trap.
Step 7: First Aid
Even tiny cuts can kill you from infection. Clean them up and avoid your death or sickness
Step 8: Light
Having a light can help you a lot. You may be walking in the night and fall off a cliff. I suggest having a light to avoid that
Step 9: Radio
Have some form of communication between you and others. Preferably hand cranked or solar.
Step 10: Tarp
You can use tarps to catch rainwater and shelters
