A university in Florida recently offered me a full-ride scholarship, however it is out-of-state, far from home, and less prestigious compared to some schools I have gotten accepted to here in Texas. I really want to go because I think it is worth it, but my parents seem almost offended of my inclination. They say that it won't be easy, but that they can pay for in-state schools. They also say going to this out-of-state university would be a waste of my potential. 

Although I concede that this Florida school is not as great as some Texas schools, I think not paying for college outweighs the drop in education. And its not like I will get a crappy education, this Florida college is good.

I just don't want my family to pay too much for my Bachelors degree. I plan on possibly obtaining a Masters or Doctorate. I also have a little brother now in high school and looking to college. I fear that either I or my brother will have to take student loans eventually. 

Am I the asshole for doubting my parents ability to pay for a better college in Texas? Or am I rational for choosing the cheapest college option?
