Are you an early bird or a night owl?Watch
Personally I'm probably an early riser despite going to bed late at university, as so many do. Having kids didn't give me much of a choice initially you switch to early wake ups, but even when I'm working away I tend to follow the same sleep pattern now and feel absolutely fine when I've actually gotten enough sleep.
I get a weird kick of energy around 8pm
Owls are nocturnal so being a night owl would mean you work better at night, like a nocturnal animal.
