I dont think you're spoiled, I think a lot of people have similar experience and its only lately that I've re-evaluated my own path through education to any great extent.
The problem is that you're not perhaps mature enough and have enough life experience at the point at which you're being asked to make sense of and use education.
On the other hand, while I would absolutely hate it if it had happened to me first hand, I tend to think the Chinese and Japanese educational cultures are going to surpass the west soon, if they havent already, they really value learning and dont have the same hang up about not appearing intellectual or intelligent which I see widespread around the west.
What I think I wasted was the opportunities to train harder physically and really make the best of physical education, although I'm saying that now with my knowledge now, I'd have loved it if PE hadnt just been half and hour of running around a hall or being given a football to kick about with. The teachers always used to marvel at how we couldnt be compelled to do that during the class but we'd all run out and do it spontaneously if someone had a ball at lunch time, that says something about the teaching etc. I'd have loved it if PE had involved lessons about muscle groups, health, avoiding diabetes and fitness training but it didnt.
When I recall school it was all more like some sort of childcare arrangement than education, technical college was much better and university I think I missed out on socialising and friends but I shouldnt have went to campuses so, so close to home and should have taken advantage of study abroad and all that, which I didnt.
Perhaps those sorts of regrets are just natural and go with growing up.
