if you were stranded on an island what 3 things would you bring?

If i were stranded on an island and i only had 3 things i would freak out. I would bring a cell phone because i could call somebody to pick me up. I wouldn't have to worry about having no signal because i have a good plan. Also i would bring a knife because then i could possibly survive. I don't know what i would use the knife for but in every survival show they have a knife so am sure it will come in handy someway. The last thing i would bring is a jumbo lighter. A jumbo lighter would help make fires. And i would not have to rub sticks together. But i don't think i would be able to survive on an island by myself.
