The 40-year-old Take That star, who penned tracks for the band such as Back For Good and Never Forget said that it is a timely way of coming up with a hit, but it seems to work.
He told Contact Music, 'I get a good song for every 25 songs I write. That's my hit rate. So I've got to go through the process of writing 25 songs to get what I think is a good one. And that's a lot of time.'
And he admitted that he doesn't know how his wife Dawn puts up with him because he is easily distracted and always on the go.
'I'm constantly not in the house, constantly somewhere else if I'm wandering around the house, and if I'm talking about an artist on my label or doing charity work or touring, I'm always obsessed by trying to move them upwards and forwards,' he added.
