A note to myself: yesterday I posted at eleven fifteen PM. It is too late for me even though it does not feel like that because I am a night owl. But as a result I fell asleep after midnight and woke up underslept. I then took a long nap and ended up having almost 10 hours of sleep (not in bed, but sleep, as tracked by OURA ring). When I go to bed at 10, I end up needing less sleep. It is very important to me to go to bed earlier even though doing so is against my chronotype.
