So your plane crashes down on an empty island and you are the only one left alive. What are you to do? DON'T panic is the very first thing people think, but actually the more optimistic you are about being saved, the higher chance you will die. Think about it for a minute, you are thinking you will be saved so don't do much in your time but wait so you probably wait for days and end up dying. On the other hand, you think you are going to die so, being a human, you do everything in your power to survive, wether it's eating bugs or fighting a bear. So having an adrenaline-rush is a very good thing BUT that's not panicking.
Surviving is simple. I will go over the 7 priorities of survival and explain some basics. They are put in order from the Wilderness Survival merit badge so you should start with first aid then shelter,then fire etc...
DO change the priorities to fit the situation you are in
DON'T start a priority that you like. I.E don't start a fire because you like it.
Read the comments as there are lots of people with suggestions (hopefully. suggest your own if you have any. ). If you think this is worthy survival skill, remember to vote for me :)
