"My advice to women in general: Even if you're doing a nine-to-five job, treat yourself like a boss. Not arrogant, but be sure of what you want - and don't allow people to run anything for you without your knowledge. You want everyone to know, 'Ok, I can't play games with her. I have to do right by this woman.' That's what it's all about." Rapper Nicki Minaj shares her advice about how to succeed in a male-dominated world.
