I can't say if your opinion is supported or refuted by biological science facts, but I can give you a piece of anecdata. I tended towards being a night owl in my teens up through maybe mid 30's. In high school I'd stay up late reading, or watching episodes of Dr. Who on PBS, or pounding away on my PCjr figuring out 8088 assembly language programming. I guess that you can say that was about as useless as "staying up late playing video games", however it did lead to a successful computer career. But the reason for working into the night was that my brain would start to kick into high gear after the day's activities. I would get into a "flow" state, and want to keep going. In the mornings I could barely think straight enough to tie my shoes, and was always tired. Even if I went to bed early I couldn't fall asleep because my mind kept racing. Now I did fairly poorly in high school, but things turned around dramatically when I started community college. Two reasons -- first, I was treated like an adult. Didn't have to ask for the teacher's blessing so that I may use the washroom. Could set my own class schedule, where taking evening courses allowed me to work during the day and got me out of the TV habit at night (that is where I learned that "Prime Time Fall Lineup" really didn't mater if I missed it). But the biggest change for me (that really doesn't work for kids these days) is that my job paid enough that I could pay my school tuition. And let me tell you something, when it was my hard earned money paying for the classes you can bet your bottom dollar that I worked my posterior off to get good grades.
