Time...a break down of an optimal (?) 24 hour day

• Sleep - optimal time 8 hours (Midnight to 8am)
• Waking and getting to work - optimal time 1 hour (8am - 9am)
• Work - optimal time 8 hours (9am - 5pm)
• Return home - optimal time 1 hour (5pm - 6pm)
• Dinner and assorted chores - optimal time 1 hour (6pm - 7pm)
• Free time - optimal 4 hours (7pm - 11pm)
• Prepare for sleep - optimal 1 hour (11pm - Midnight)

It seems so simple doesn't it?
