What I couldn't live without

Mhh one thing in which i couldn't live without if i was stuck on an island i would 

try not to pout, cause i could bring my phone to help out or someone like a boy scout 

or maybe a spear for catching sea trout, or maybe a lot of water in case of a huge 

drought, or possibly a compass so i can choose the best route, but it depends on the 

island, would it be like a fallout, what would be the layout? Would I have a hideout 

although i'm going to have to sellout without a doubt and say i'd bring about my 

family because when it comes to bringing joy they don't holdout they go all-out.
