At times having to go to sleep is a pain. If we didn't need to go to sleep we could get so much more done.
However, on the other hand, if we didn't sleep we would be bored out of our minds. Everything would be done, Everything would be clean, dusted, vacuumed, mended, sewn, crafted, written, read, painted, built, repaired, listened to, watched, decorated, moved- the list goes on.
And we wouldn't be able to have dreams - daydreaming just wouldn't cut it!
