My experience at Cornell had been a whirlwind of endless opportunities. It has absolutely had it's ups and downs, with times where the stress and fast pace of classes seems to be unbearable, but usually when that happens a break was right around the corner and there was time to catch up. All the students at this school, from the engineers to the Hotelies, are used to being the top of their class in high school. It takes some getting used to learn that not everyone can be the best at this university.
That being said, Cornell can offer you the change to truly impact the world in whatever field you pursue. Your plant science degree with lead to cutting edge research, your business major with give you connections others need years to build and your engineering degree will give you your choice of career straight out of college. But that diploma does not come easy, you will have to work relentlessly for four years to earn it (five years if you're studying architecture!).
Looking back to choosing this university my senior year of high school, I wouldn't change a thing. My experience has been far from perfect: I've experienced failure just like the rest of my peers. I'm not, however, the same person I was in high school and this is a good thing. Cornell has changed me for the better and I highly recommend you let it do the same to you!
