Imagine you have to spend a week on a deserted island. What are 5 items you'd bring with you and why?

If I was stranded on a deserted island for a week the first thing I'd be sure to pack is sun screen!  My biggest fear would be exposure to the elements while trying to forage for food, build a shelter and come up with a game plan to be rescued.  My 2nd item would be some form of fishing tackle, I assume the easiest thing to catch out in the middle of the ocean would be fish. I'd be sure to bring plenty of hooks, line and artificial lures in my tackle box.  The 3rd item I'd be sure to pack would be a fire-starter.  I would choose this over matches because flint/steel work while wet where matches become useless pretty quickly when wet. The 4th item I'd bring would be a guitar, there's something very relaxing and peaceful about music while you're alone and I imagine it would help pass the time.  The last item I would bring would be a picture of my family.  That would keep me going in even the darkest of times. When the fish aren't biting or the weather isn't cooperating - knowing I have a lovely family to get back home to would provide all the motivation in the world to keep fighting!
