I've started doing this recently based on our discussions here, and I've noticed that under different states of arousal. And here I'm talking specifically about sleepiness versus alertness type arousal when I wake up in the morning or when I'm tired in the evening, where my mind is at, where it defaults to and what I'm paying attention to throughout the day is that just asking myself to notice, and I've certainly noticed some patterns.
