The Extent I Would Go to Survive

So. Let us say I am stuck on a remote island with nothing but the clothes on my back and my wits. I would do everything in my power to survive- except maybe cut of my own arm- to survive. However, seeing as I'm a small girl with no upper arm strengh, I would probably die the second anything tried to attack me. Like a lion, or a tiger. Or maybe even a bear. (Oh, my!) However, I would do whatever is in my power to survive, like using common since, finding water, and building shelter.
