Gary Barlow thinks he's a different person to the one he was at 21 years of age.
The singer-songwriter has said that while he could cope with extremely tight deadlines during his Take That years, he doesn't think he could pull it off today because he doesn't have the same confidence despite his years of experience.
Barlow, 49, shared in an interview with the BBC that Take That's management needed an album written in a week in 1994 and he managed to write hits likes Back For Good and Sure for the band’s Nobody Else album in the short timeframe.

"You do it just because that's what you've been told to do," he shared. "You don't think, 'Wow, this is so much pressure, everyone. How can I do this?' You just get on with it.”
Barlow went on: "I was full of confidence at the time because we were having hits all over the world. And that is a good place to be as an artist.
"I'll be honest, I don't think I've got that kind of confidence anymore. I'd have been 20 or 21 when those calls used to come in. And that's a different person.
"I wouldn't trust myself now to think I could do it in a week."
It comes as Barlow has released his first solo album in seven years, Music Played By Humans.
The new record sees him collaborate with a number of famous faces and also includes a comical duet with James Corden on track The Kind of Friend I Need.
