Describe how you have taken advantage of a significant educational opportunity or worked to overcome an educational barrier you have faced.

Hello there-
This essay is aiming to show the struggle of the applicant in an educational barrier and how he fought to overcome it.
Original detailed description is below:
Describe how you have taken advantage of a significant educational opportunity or worked to overcome an educational barrier you have faced.
Things to consider: An educational opportunity can be anything that has added value to your educational experience and better prepared you for college. For example, participation in an honors or academic enrichment program, or enrollment in an academy that’s geared toward an occupation or a major, or taking advanced courses that interest you — just to name a few.
If you choose to write about educational barriers you’ve faced, how did you overcome or strived to overcome them? What personal characteristics or skills did you call on to overcome this challenge? How did overcoming this barrier help shape who are you today?

Please only consider the option of overcoming an educational barrier.
Here is the story I want you to write about:
The applicant has been the top student in school and his specialty is math. He is very proud of his math talent and started to grow arrogant (too proud of himself). He once gained a chance to participate in math competition which was said to be really difficult, his arrogant blinded him from preparing for the competition and costed him the chance to win the prize. (Like, he made many careless mistakes and got stuck at difficult questions, maybe add his thoughts at that time, anxious, nervous, started to realized not preparing was a bad idea, etc.). After the competition he learned there are a lot of great people at his age with outstanding math knowledge and started to be patient and gained strong will in overcoming the barrier that keeps him as the top math student in class but this time he is not just talented but also hardworking. So the educational barrier in this case is not about not learning stuff well but being too talented that ignored the importance of hardworking, patience etc. and he also gained strong will from this experience.

The “barrier part” of the story may be very different from the traditional ones, so please think carefully in how to demonstrate it, so that we are showing this process instead of telling this process.
Please make the paper fluent and consistent, add logical linkages in between to ensure the logic flow of the essay.
