That's cool bout your girl putting in 50 hours a week working, but I guarantee you Kim is putting in more work than her. Being in Kim's position is 24/7 job not just 50 hours a week.
When determining how hard someone works I feel hours worked is second to what they actually do. Not trying to knock Kim's hustle and not saying I know all the details of her business endeavors but from what I do know her " job " doesn't seem THAT hard. Like the guy said above how how hard can photo shoots, saying yes to endorsement, and letting cameras follow you around be. It's the people around her that pretty much do all the work, the photographer shooting her photos, the lawyer reading her business contracts, the video team editing her footage. What people what from her is her physical look which really doesn't take much mental or physical effort to yield. Let's be honest, God already did/does 90% of her work for her.
