If you had to spend the rest of you're life on a island?

Survivalist guidebook/handbook - so I could have something to start me out on how to survive. 

A large machete - so I could use it to cut things with. 

Water filtration system - so I could try to filter out the salt from sea water or filter any water I find on the island.

An airplane, a pilot, and directions back to my house. 

Only one Island for me and it's Summer Isle

I would take a ship loaded with all my possessions and then some.  Yeah, I know that's only one thing, but it's a compound thing.

I would set up my island as a resort and invite all my friends to come.

A knife (without it you're dead since you couldn't even cut your food), a lighter (to build fire) and a bottle (to fill with water)

a satelite phone, biggest bottle of water, and a box of pizza
