The worst time of day.

1-4

Peak activity (when possible) or futile attempts to fall asleep.

5-8

Regardless, I'm asleep at this time. Sleep won't let you down, sleep won't betray you, and so on. However, waking up at seven in the morning is a drag.

9-12

Conflict of interests. External interests require productive work, but the brain hasn't woken up yet.

13-16

Finally, I wake up and can produce something productive.

17-20

Evening autism.

21-00

The beginning of the peak activity; all the brilliant thoughts and ideas come to me at this time.
