Why is Jack so desperate to return to the island?

• A hot piece of ass like Juliette is hard to find these days.
• The island gave him mysterious powers such as "not being addicted to painkillers."
• He forgot his keys.
• There are dramatically less car accidents.
• Nobody understands him and everyone else is stupid.
• He never finished carving that really cool slot car track.
• He has been training intensely and finally feels ready to take down Hurley in Ping Pong.
• He accidentally left his favorite watch inside of Ben.
• Kate in a bikini.
