"I don't even know how I make my schedule work it really is just mind over matter. Like, you've really gotta will yourself to do it, because sometimes I feel so overwhelmed, like I'm not gonna get this done," Minaj told Access Hollywood.
"I just have a desire to be that kind of woman that I look up to when I was young. That kind of woman like the Oprahs and the Madonnas," she said.
"Those are the women that I look at and I'm like, 'If you can do what you do, I can do this,' because what I'm doing is such a small fraction of what their days must be like", she added.
Part of Minaj's drive comes from the desire to stay relevant in the ever-evolving music world.
"I definitely do feel the pressure to reinvent. I think any artist would be lying if they told you they weren't. That's just a normal human feeling. You're in a business that's constantly changing and because we're in this internet era, people see things one second and forget it the next. And it's like, you know, you've gotta be really special to stick around", she said.
