I'll tell this to the cleaning lady who works for a living 12 hours a day. Her 12-hour schedule is the only thing holding her back from truly fulfilling her dreams. I'll tell her 4 or 5 hours is really all she needs to do. When her hungry children come begging for food and her landlord comes asking for the rent, she can tell them that she's just maximizing her productivity and her leisure time, and that they should do the same if they want to live a truly productive and meaningful life.
