Generally speaking, living in the wilderness is all about survival. This basically falls into 2 categories and it is staying alive and utilizing the wild as a new way of living. The primary emphasis is to learn how you can live on your own, use the resources surrounding you to stay alive and yet, keeping yourself nourished and fulfilled.
But before anything else, you have to determine the proper action to be taken. Action that is good for you but also, appropriate for the environment while taking into account of the climate, resources and the likes.
Having said that, you need to learn survival skills too as per the condition in the place where you wanted to live.
On the other hand, just before you rush to your decision, consider taking a couple of survival classes including the necessary survival skills you’ll need. It is best that you have undergone some sort of training before braving the wild. You may contact a handful of adventure organizations or wilderness groups in your area to know about their personal experiences and suggestions when out in the wild.
Also, you must gather the necessary items and belongings in your backpack with everything that needed before you proceed.
