The author's experience is very similar to my own–my parents called me 'the sleepless wonder' when I was a kid, and by high school getting out of bed for morning classes was excruciating. In college I mostly chose classes that started later in the day and wound up doing much better academically. Since college I've made a point of taking jobs that offer flexible hours, which thankfully seems to be increasingly common.…
I spent high school thinking I was exceptionally prone to getting songs stuck in my head. It turns out that I just get them stuck in my head when I'm extremely tired, and that state was so continuous that I never noticed there were times it wasn't true.
That's a relatively harmless example, but I do seriously wonder how I spent ~8 months/year for 4 years getting 2-6 hours of sleep per night. Getting that amount of sleep distorts everything from my personality to my ability to drive safely, and it's more than a bit alarming to me how little attention we pay to what it means to have teens spend most of their developing years shockingly sleep-deprived.
