In a new video released ahead of The Voice's return on Sunday (February 5), Levine said: "What I found last season through The Voice was that I kind of love helping these guys out. Every step of the way was really fun and I looked forward to going to work the next day.
"It was this new, exciting thing and a totally different angle I'd never explored before so The Voice actually kind of changed my life. I want to continue to be excited by this whole strange, amazing journey. The show really inspired me last season and I want to be inspired again."

Levine also said that season one of The Voice had "set the bar high" for the season two contestants because Colon had been an "incredible" winner.
"I knew from the first moment I heard him sing that he would win," he said. "He's the best singer ever, just an incredible talent, and I'm happy that he won.
"Even if you're a singer in the competition you kind of had to be like, 'This dude is going to win this because he's an incredible singer'."
However, Levine added: "That being said, now he has to be an artist. Winning a singing competition is very different to being an artist. It's a whole different set of tools. That's a new challenge for him but we got him to the promised land, to the starting line."

The Voice returns for its second season immediately following the Super Bowl on Sunday, February 5 on NBC, before settling into its regular Monday night slot from February 6.
It has been reported that Levine and fellow mentors Christina Aguilera, Blake Shelton and Cee Lo Green will collaborate on a Prince medley on the Monday, February 6 instalment.
Host Carson Daly recently teased that the season two talent "far surpasses" that seen on the first season, saying: "Our show is as good as our talent, that's why people tune in. The stories and talent in season two is above and beyond. The competition is going to be intense."
Christina Milian will join the show's second season as social media correspondent.
