I feel this. I'm a naturally night owl. I've had years of being more productive at the office between 5 PM and 8 PM than the entire time between 9 AM and 5 PM.

I feel this. I'm a naturally night owl. I've had years of being more productive at the office between 5 PM and 8 PM than the entire time between 9 AM and 5 PM. For a while, a sudden burst of productivity was the thing that let me know I was at the office late. Conversely, I also have a tendency to wake up with the sun, full of energy, when there's sun (and, living in Vancouver, that's about 50% of the time on average). Then... I had a kid. This morning, I was awake at 5 AM. Got up to go to the bathroom, went back to bed, started drifting off, and then what felt like a herd of elephants came storming into the bedroom, climbed into bed, went for some cuddles, and then just started thrashing around from being bored. Guess I'm awake now, then.
