Niall figures he was a bit too carefree, explaining, "I think I was probably quite an annoying teenager. I'd teach myself how to know a situation." Liam added, "You just loved life; you still do today. That's why we love you." Aw.
Then Liam was quick to note that Niall needed a bit more grooming for the media in those early days, explaining, "Niall had a really bad streak...for always saying the wrong thing at the wrong time."
Niall admitted it was true, adding, "I just wasn't used to all of this. But now I know what I'm doing. So I think I'd tell my 14-year-old self to maybe grow up a bit before you do this!"
As for Liam, he says he might have been a bit less serious about everything, explaining: "I'd tell myself to lighten up a bit. I was just a bit too work-concentrated, because I really wanted to make it. I'd rather have just enjoyed it a bit more. But it kind of helped us along, me being the serious person while everybody else was erratic. I was the serious one."
