The father-of-two from Connecticut won the $100,000 prize and recording contract over runner-up Dia Frampton on the show's live season finale in June.
Speaking to Jay Leno on The Tonight Show, Colon said: "This is a new lease on life. Before the show I was just a struggling musician trying to figure out a way to support my family and this show came along and completely changed everything."
Leno then quizzed Colon on which bills he put on the backburner, to which Colon said: "We had a little game, my wife and I, of, 'Well, we can't pay this bill this month, so let's try and pay another one'.
"Usually the cable bill was the last one to be paid. I'd get the notice for my cell phone bill saying, 'We're going to shut you off if you don't pay it right now', so I'd pay it the last day before they shut me off. That was life."
Colon, who was mentored by Adam Levine on the show, also revealed that his daughter had been supporting fellow finalist Vicci Martinez, although he admitted that he didn't mind because it showed she had good taste in music.
"The kids are proud of daddy," he said. "My oldest was a big Vicci Martinez fan. She was rooting for Vicci, but that's OK because as long as they like good music that's all I care about. Vicci is awesome, so I was OK."
The Voice returns to NBC for its second season in 2012.
