In all seriousness though, you would follow the proper priorities (first aid and safety, shelter, water, signal, fire) and then take stock of your environment. Find what resources are available and what the possibility of rescue is (proximity to population, sea or air routes). If it looks like rescue may be far off, start setting up your living quarters, gathering resources and make your signaling devices, like a very large SOS that could be seen from the air.

After that it is waiting and trying to maintain a positive attitude. Get comfortable, try to sleep well and keep yourself occupied improving your situation.

If you can make a hammock and pina coladas from the coconuts, all the better.
