What school you went to will not matter all that much when you start working, just like what high school you went to does not matter once you get into college, etc. If you are using the ivy league wish to try to force yourself to study harder, I'm not sure it will work too well; I tried something like that, wanted a particular grad school in a particular field and ended up having to change majors I did so poorly (didn't study) in that field.

If I were you, I'd figure out what you want to do and use that to do well in school; it took working on my second degree to do that for me, in my 40's and 50's. What you can learn across your lifetime is the same for everyone; our great grandparents back 150-200 years ago (my great grandmother graduated from university with an accounting degree in 1881) learned to read and write and do arithmetic just as well as I did; I have grandparents who only had 8th grade educations and were a success and those who had graduate degrees from top schools who were not particularly.
