You are all alone, and help won't reach you for another six months. You have a supply of food and water which will last until help arrives.
What are five things that you take?

A jug (for water), an axe, long length of rope (as long as possible), a bow, 2 dozen steel arrows with sharp barbed tips. To start I'd look for water and then fashion myself clothes, weave a hut & make a quiver (as I already know how to leathercraft in real life, shouldn't be hard). That would be my basic strategy.
