What I'm finding, though, is that when I get uninterrupted sleep now, it's amazingly refreshing. I think I know how to operate on little sleep for extended periods of time now. When I get to sleep uninterrupted, I feel amazing energy the next day. And when I string together a few uninterrupted nights, it's even better.
I hope to keep the healthy sense of urgency I have in my work time now. Having a young kid keeps me very focused and efficient in my work time, because I know I can't just put in extra hours to get things done. I hope I keep that healthy urgency, but I'm aware it could slip away as I take full nights of sleep for granted again.
