Somebody in my neighborhood did a Craigslist ad for a bunch of free stuff. It was one of those "must take all" deals. All the crap was accessible from the street.
So somebody came up, grabbed what they wanted and left. Dude went out screaming at him. The stuff that was left was total garbage. I love it! 😈😈😈
Every second night; sleep for 9 hours and wake up ready to take on the world.
Every second night; sleep for 5 hours and wake up wondering what the fuck is going on.

I think it was one of Art Bell's guests who talked about sleep being like a bank needing a steady balance.
So you sleep 5 hours one night, your body catches up the next night. Maybe if you just got 7 hours of sleep you would do better consistency wise.
