The 'Keeping Up With The Kardashians' star oversees the careers of her six children including daughters Kim, 32, Kourtney, 33, and Khloe Kardashian, 28.
The 57-year-old says she finds it difficult dividing her time equally between all of them but tries to strike a balance between her roles as their mother and manager, reported Us magazine.
"I feel guilty all the time because I can't be everywhere at once. I feel like I want to be there for everybody, whoever needs me, I just worry about them all," Jenner said.
Jenner earns 10 per cent of her daughter's pay cheques and thinks they are happier when she pushes them to work harder but insists she has never exploited them.
"My girls are not pansies. But I think everyone needs direction. My family could have said, 'Are you out of your mind?' But everyone was excited," she said.
