Oh wow, I remember! I get 10 hours a night and I will NEVER sacrifice sleep. It's too painful. Even with 5 kids; we go to bed around the same time, though they usually get more than 10 hours (11-12). I sometimes clean for a while. Sleep is absolutely my priority for myself and my family.
In high school all I did was go to bed by 10 and get up at 6:30am. I was so tired I wanted to shrink back to bed. I had a sports practice 6 days a week after school. But all in all I did not skimp on sleep big time. I studied and never went out.
Now, as a mom, sleep is #1. I do not understand how some people can skimp. I get 10 hours a night to feel good all day. I NEED to in order to be a good mom and keep up. I go to bed with the kids or a bit later (to clean) and we wake for school, which starts a bit before 9.
For a bit in high school I'd stay up late to read, then one day I crashed real early and woke up feeling GREAT. I did not know what I'd been missing, and never again did I skimp on sleep.
