I'd suggest based on empirical evidence most people in the tech world are more apt to flower later. So for some, their peak was at high school or college - for most of us, I suspect its early to mid thirties.
So, all, told, I was working _80 hours a week, minimum_ in my high school years. I graduated top ten in my class, and my parents were astonished that I took two years off between high school and college going to a technical school eight hours a week with a 40 hour a week job. I had cut 32 hours of work a week out of my week, and I was only 19!
When I finally did go to college, the weeks during the semester were about twenty hours a week between classes, studying, projects, and tutoring and a twenty hour a week part time job. I can understand why you felt like college was a vacation because I felt the same way!
The downside to all of this is that I was very poorly socialized, compared to some of my peers, when I started college. Luckily, since I had a bunch of free time, it was easy to catch up, but the first semester was difficult for me navigating all of these unstructured, unsupervised socialization opportunities. A part of me regrets that because that stunted my ability to network from the start of college - I have no idea what opportunities I have missed out on and will miss out on in the future as a result.
Several people that graduated in that top ten with me who had the same 80 hour a week work week in high school could not handle the unstructured free time in college. Two dropped out of college but have none-the-less worked their way into lives that seem to make them happy, one got heavily into drugs and is still in jail, one committed suicide, and the rest graduated and seem to have kept on the track.
The obvious question is whether weedout regimens actually burnish skills. In my experience they did to some extent, but most of the effort expended was game-playing to get onto a path which would be easier or more lucrative in the long run. (Example: becoming a medical doctor or tenured professor is harder than it has to be because people are attracted by the prospect of a job-for-life.)
It's pretty frustrating to bust your hump in high school to get a leg up on college work and then be stuck in the same class as the mouth breathers who just coasted by in high school and completely bored.
But yeah, coulda CLEP'd out of at least a year of college if I'd known better. No-one told me that and I didn't figure it out until it was too late. Never even occurred to me that I could knock out all those credit hours on the cheap with some very, very light studying over a summer. I mean college is supposed to be really hard, right, otherwise what's the point? eyeroll
This is one of most baffling aspects about the US, that is that you can have classrooms with no windows. I didn’t personally grow up as a kid in the best social-economic regime (an Eastern-European communist country in the ‘80s) but fortunately for little kid me the regime’s architects and urban planners put great emphasis on all classrooms having lots of windows, as big as possible. I later in my life became quite interested in the history of architecture and urban planning and I was able to find this idea (i.e. big windows are good for schools) in architectural magazines published way back in the 1950s.
I suspect that's a natural consequence of good people being held down in poverty by tyrannical government.
My high school was horribly inefficient, in other words, which ended up being stressful. I gather this is the norm. Meanwhile adults were telling me those were the best years of my life—I mean I wasn't really bullied and had a pretty decent high school experience and now that I'm older I sorta get what they meant but god damn, if that'd actually been true I should have offed myself. The "real world", and college, are easier than high school, which was difficult mostly because it was both hyper-authoritarian and wasted phenomenal amounts of time.
