The 26-year-old tailor was noticeably absent from the last series of the Essex show but says that time out was what he needed to realise how lucky he is in life.
Mario told The Mirror that it had been difficult to watch his co-stars on screen continuing on as normal without him but, on reflection, it was a blessing in disguise.
"At the same time it was a needed break, I think. I've been doing the show for three years and I think my attitude had become a bit lacklustre. I 'd become a bit arrogant," he explained.
"I think I needed a reminder that I'm very fortunate to be in the position I'm in."
Mario was temporarily suspended from TOWIE earlier this year, and Mario later said his time off from TOWIE - which included missing the Marbs special - had come amid "a few personal issues", admitting he had gone off the rails and been partying heavily.
A show rep told Reveal of Mario's absence: "It was mutually agreed ahead of Marbella that Mario would take some time out from TOWIE to address some personal issues."
Now, however, the handsome reality star is back in the fold, and is currently over in Ibiza filming the brand new series of TOWIE with his castmates.
He was pictured on Sunday night escorting co-star Gemma Collins to dinner alongside his best friend Charlie Sims and Charlie's girlfriend Ferne McCann.
