The Patience hitmakers - who have earned millions since they reformed in 2005 - say they often get disheartened by their writing and are constantly questioning their own abilities.
Jason Orange said: I’m the most negative in the band, asking, Can we do it better? all the time. I always question if what we are doing is good enough.
His bandmate Mark Owen added: Sometimes one of us has to go down a certain path with an idea before we all decide it’s s**t.
However, Howard Donald says the group perform better as a unit now as Gary Barlow is no longer the sole songwriter.
He explained in the Take That Presents: The Circus Live DVD: We’ve got a much bigger friendship now that we ever did.
Gary used to write everything at such a rate we were always catching up.
Mark - who had two top 10 singles in the UK chart after the band split in 1996 admits his own input in the band would be better if he could remember his dreams.
He explained: I write great songs in my sleep. I sing lyrics into my phone.
When I wake up in the morning it’s just me mumbling and falling asleep - but when I’m dreaming I hear all the string arrangements.
