Some people like the idea of braving a disaster on their own. They want to break off from their group, or they want to start on their own completely. If you want to try survival on your own, there is one question you have to ask yourself.
Have you passed the sole survival test?
You haven’t passed the test unless you have been on your own in the wilderness for months at a time. During that time, you need to have gathered your own food, made your own shelter, and done everything you needed to survive. If you were able to handle it, then you can go at it on your own. If you have never done it, then you need to go with a group.
As tempting as it might be to go at it on your own, survival is easier in groups. You can work together as a team to get the job done, so stick with your group.
