Personally, I got humbled early on when I realized that I wouldn't be able to read all the interesting books in the world. I wouldn't even be able to keep up with just the new interesting books being published. A very sad day, that was.
It was a simple matter of reading (and not quite understanding) a few real books aimed at researchers to see that some people were far brighter than me. Just like some were far better at drawing or playing football or high jumping. I count on someone (or many someones) being better than me at absolutely every single thing that I might be good at. Hopefully, the talent profile I have will be good enough anyway, especially if I work hard and avoid winner-takes-all areas.
(It did take a long time to learn how to apply myself, though, after so many years of enforced boredom.)
I challenged myself with the simple notion, "If I'm so smart, I should be able to ace any of these classes" and I simply worked my tail off until I did.
I over worked for a while until I was satisfied that I understood the "how" of studying and then learned how to do it more efficiently and slowly ramped up the course load.
I didn't finish my undergrad with a 4.0, but darn near it, and I fairly coasted through my grad program and still nailed above a 3.5.
It all boiled down to those boring couple years where I really challenged myself to learn how to learn, because up until that point school had come so easy I hadn't bothered.
Fortunately (for me) I had a not so good HS Counselor who I never met and who never explained to me that it was possible to go to college without having rich parents.
So I joined the Army straight out of high school, and that's where I learned how to work my ass off. Not mentally so much, but in general how to have an expectation of myself that I should always keep pushing myself to do better.
That was 25 years ago mind you. Your mileage will definitely vary.
Yet, before one enters an university, teachers almost universally refuse to answer this question.
The lack of this intended benefit of education is what allows talking heads to polarize society by shouting past each other.
One thing that certainly helped me was to take a slight detour from my graduation path for a semester to take classes that genuinely interested me. I found that taking a few courses where I was more willing to put time in out of sheer interest helped hone those same habits for classes which maybe were less interesting / more tedious.
Hope this helps, and best of luck!
1. Choose your peer group carefully. Your values will shift to those of your peers. In high school my friends were the smart kids. At first we were highly motivated and competitive and earned high marks, but that didn't sit well with the rest of the class. We got excluded for being try-hards. Therefore the new game was to pass the class with the least amount of effort. When I went to college I associated with similar people. It was cool to pass with the least amount of effort. Make friends who have values that you want to have: people who value effort, not talent.
2. Don't fall for the incentives trap. Your success gets measured by passing classes and getting good grades. It's natural for humans to game the incentives. Your motivation shifts to doing well on the incentives. Instead view passing the class as a bare minimum. The goal is learning, the test should be an easy byproduct.
3. Learn how to handle failure in a healthy way, otherwise you'll find yourself avoiding things that may lead to failure. When failure does come, try to stay positive. Don't try to keep up appearance of success. Be open about your failures. Find somebody you can talk to 100% openly; a friend, your parents, your gf/bf, a sibling. Make sure that your self worth isn't reliant on your success.
4. Don't rely on willpower. Using willpower is a losing battle. Design your life so that you don't need to rely on it. Set up meetings to do your homework with friends. Build good habits. Beware of slippery slopes. Now you're skipping class once, in a year you're skipping class entirely.
I coasted through community college as well (including classes considered difficult) still bored and getting As and Bs. I probably needed to have cared more in high school and gone to a harder college for me to get the wake up call to learn to study.
As it is, I learn on my own time and program. It's not the worst, but I always wonder what I'd been capable of with more motivation.
I can imagine that having to learn how to study (and developing the character to actually do it) is something that takes time and commitment, but if everything else is so easy for you, surely it can't be impossible?
Studying is more of a practice/habit, than an area of knowledge; someone that has avoided needing it because they pick up knowledge well without it and hasn't had their ability to pick up knowledge challenged isn't necessarily going to pick it up easily, especially, if they have many years of strongly ingrained contrary habits when, suddenly, for the first time their ability to gain knowledge is stressed and they need studying to keep up.
Sure, its not an impossible skill to develop. OTOH, when you've missed out on many years of before-college skill development in it and try to catch that all up in time to make a difference once you get to college, its not all that likely to succeed as well as you'd like.
The weighting of college admissions exams (which are heavily weighted toward measuring ability rather than study skills) and high school grades (which measure a combination of study skills and ability, such that you can't pull the two apart distinctly) in admissions means its easier for someone with high intelligence and weak study skills to get themselves in over their head in the college program they are admitted to than for someone with less intelligence and stronger study skills to do.
Plus, the difference between not having study skills and needing to learn them from scratch and having study skills but needing to study more is one of kind, not merely of degree.
(But, sure, lots of people have transition problems with college, even though those problems can have different sources, natures, and manifestations.)
Fast-forward a few years to college, and it turns out that I have no idea how to study, how to push myself to do the work required for classes. I had a very hard time turning that around.
