"I got such a lust for life and I feel like the crazier I get, the more mental barriers and more confidence I get. Thats where it comes from. Its just the determination and lust for life."I feel like Ive lived a hundred lives in the span of my lifetime. Ive done so much and a lot of it comes from not having any fear. I have no regrets. Ive gotten the absolute most out of life. I could die tomorrow and totally be at peace."Allin is taking that mindset into New York City. Since winning the AEW World Championship, hes been on a tear knocking down any challenger that has stepped up to him trying to knock him off his pedestal.While hes certainly proven to be worthy of holding the title, he said theres still more to be done."Theres always something to prove," he said.

This Sunday at Double or Nothing, thats the biggest thing I need to prove at the moment that it wasnt a fluke win."Allin is sure he can beat MJF in his home state and take a piece of his hair home, too."Make a voodoo doll and torture him for the rest of his life," he said.CLICK HERE FOR MORE SPORTS COVERAGE ON FOXNEWS.COM Double or Nothing will take place at Louis Armstrong Stadium in Queens, and it promises to be a card jammed with hard-hitting action.The card looks like this:Allin said pro wrestling fans who have never seen an AEW show before are in for a treat."The unpredictability of what AEW is," Allin told Fox News Digital when asked what first-time AEW watchers could expect.
