How did you adjust to your college life?

How did i adjust with my college life? I know that being a college student is a tough job. That's why there are some things i need to adjust, like me, being very silent, how can I make friends with others if i will be very silent? That's why I changed that, that's why as of now, all my classmates are my friends already. Second is, I am learning now to be more responsible because I can hardly feel as of now that college life is a lot harder that my high school days.
