Can You Cope With More Than 2 Blogs?

I wonder how some bloggers cope with writing paid posts for more than 2 blogs. I know some bloggers even have a dozen of them and plan to purchase more domains. I wonder where they get so much ideas to write and write and write. They earn 5-figure income each month and I think they even plan to earn more if they can. I wonder if they ever get more than 3 hours of sleep each day. I'm already struggling with 2 blogs and if I create another blog, I don't think I'll have time to eat, sleep and shit, seriously! I'd really love to have a peek in their daily lives and see how they cope with their kids, paid posts, cooking, household chores, taking care of hubby, mil and what nots.
