There are a few basic things we need to survive:
- Water
- Food
- Shelter
- Heat
- Company
Your most essential piece of kit is a knife, or something to cut with. A knife will increase the likelihood of you having spare capacity of the elements listed above. For example, you can drink with your hands, but if you carve a bowl, it is more efficient because water does not pour through it and it gives you somewhere to store water.
Once you have survived, you need to rebuild and prepare to flourish.
Although most people think surviving is about food, shelter and water, the soul also needs to survive. Culture, arts and learning also need to be thought about when rebuilding.
