Nicki Minaj is a super mega star right now. The key to her success has bee long days, out side of what she is used to.  But her new gig actually gave her discipline.  She recently discussed her new commitment to popular reality music competition "American Idol" and how having the duties of a show panelist keeps her disciplined.

"When they mentioned it to me, like, last year, I thought they were joking. [Producer] Nigel came up to me and said, 'We want to talk to you about being a guest judge.' ... They're very long days, I'm not really used to having to show up somewhere at a specific time. I've kinda been my own boss for a few years, so this is like adding discipline back in my life. This is adding that strict regime of having to do something. Everybody's affected by what I do." (E! News)
