When you give your description try to remember that initially you would know nothing about the island, only that you have seen a Andrewsarchus and a Giant Sloth..
You can describe how you would use different people (if you assume they'd follow you and not one of the other groups) and how you would deal with people who have gone crazy. Obviously your profession is whatever you ACTUALLY know (so don't act like you are a doctor if you aren't, lol, you don't get Google on the island).
The only items you have (that are yours) is whatever you'd normally bring on a vacation to Guam.
The day you start surviving is the morning after the Sloths attacked the plane, you wake up during the riot after the pilot was killed.. initially you don't know the pilot is dead, you just wake up to pandemonium.
:EDIT:
OK, so if your English on a plane full of Japanese people that may be a problems lol, just assume that you can speak Japanese. Other then that, make it as real as possible.
