I don't think you should mix "substantial change in personality from high school" with "living on campus". There are probably millions of college students who live on campus for four years and make very little change from high school. And there are millions of commuters who do. And there are many people who don't attend college at all who change. Etc. There is not one path toward personal growth.

I'd say more than anything else, focus on making real friends, and hit that hard. It doesn't matter what the manner is that you encounter them; one of my best friends from one era of my life I met because he got food at the job I worked at. Others were from classes. Reach out to people whenever you can, and see if you can take a genuine interest in them.
