If you had to go to a isolated island by your self, and you could only bring 5 thing what would they be?

Internet-Spam-cheese-bed-toothbrush!

I would take - an insulation blanket that could double up as a shelter from the elements. My 2 dogs, chocolate and drinking water.

If its an island off the coast of Norway my 5 items will be 5 sleeping bags

Does the island have wi-fi? Personally I would hate it. Can I just have a corner of a 5* AI Caribean resort insted? LOL. 

I wanted to bring my solar panels but the transformer to convert it into 240v ac suitable for plugging in a device would have counted as an extra item out of the 5. Maybe I was overthinking it... 

Think bigger.

A satellite phone, a high-quality campervan, a ruggedised laptop, a container load of MRE rations, and a load of solar panels to provide all the power I need. 

That would suit me.

Humm...

a hat, a towel, a good soft pijjama, my glasses and a knife.

Simple 

1) My bed - so I could stay snuggled up in perpetual escape from the world

2) A podcast playing device (phone probably) - I’d be listening to dramas/documentaries/ghost stories/true crime whilst in bed escaping from the world

3) My headphones - see above

4) My entire collection of Nerina Pallot albums - just love her music and listen to her daily while escaping from the world, usually on my journey to work.

5) My entire ‘Jack Reacher’ collection (by Lee Child) - so when my ears needed a rest I could escape from the world through reading my favourite books.

The End

A harpoon, my phone, a stimmer, soap and washing powder.

I keep thinking of Wilson from the film Castaway. 

WILSON I'M SORRY! 

Everyone needs a Wilson to talk to. 

A fishing rod (to catch food); a good Swiss army knife (to prepare food); a cooking pot (to cook food); a flint-stone lighter (to light a fire to cook food over/keep warm) and a large plastic bottle (to filter water).

There's always that 6th thing isn't there. I thought for a while about some kind of soap or disinfectant instead of the pillow, but the pillow won

All very good answers, I think I would definitely take a spear gun, chisel, saw, rope, 100%alcohol. 

Mmmm, think I'm a bit less practical! First things that sprang to my mind were: teddy bear, very big book, notebook & pen, chocolate and big duvet! 

Boat, compass, waterproof map, sextant and waterproof guide book on traditional navigation methods.

OK now the intended way..

Knife, lighter, tarpaulin, pillow, and a saucepan.

The thinking is I'd gradually learn the skills I need to make fire and shelter, but assuming I got there without the skills in the first place, these objects would enable me to survive the first month or so, long enough to acquire the skills. 

A chef, a fisherman, a Doctor, a dentist and a handyman!  Lol, sorry, I couldn't resist that 

Once I got that in my head it completely blocked me thinking of a proper answer
