what would you do with the other 21 hours a day?

Shoot, the list is endless. Off the top of my head.....

Exercise
make love
learn a new language
play more with my son
develop new business ideas
finally do the photoreading course I've had sitting on the shelf for years

I’d love to be able to adopt this sleep system. Just not sure how viable it is if my family and clients aren’t on it. Would free up net time but would require nap time during hours I need to be available for clients. Gotta ponder this....
