Welcome to college. It's all on you now. No one is going to force you to do or not do something. Everything you do from here on out is on you. Make what every choices you want then live with the consequences.
Over my college years, I came up with some guidelines for being successful at college. After college, I've added some to be comfortable in life.
Also, these are just guidelines based on what I've been told ( and have found to work) and experiences I've had, life is big and weird and unknown you won't find all the answers here or anywhere else, follow this guide them as much or as little as you want.
Have Fun!
