It is your buddhist practice that will keep you open, curious, loving, and dedicated when you meet your college responsibilities and social freedoms.
Now is the time that your spirituality will begin shine through whatever you do. Being buddhist is not what you do but the way you do things, the way you approach life and identity.
A buddhist knows there is no such thing as an inherent identity. Everything is just a collection of interconnected influences coming together and falling apart in the dance of form and formlessness.
As such, what is there to fear? What is there to desire? You move with the dance and it’s no big deal. Yet it is quite wonderful as well.
Really put the effort in to maintain a bit of a daily practice. Try to do a bit of meditation every day, read a bit of scripture every day. It doesn’t need to be a lot; being a freshman in college is a robust experience. But maintain touch with buddhism to the extent that something about it is inspiring you every day.
A buddhist book that I am always recommending, that should be a handbook for life in this modern society, is The Places That Scare You by Pema Chodron. In it are many useful and life-changing practices that will help you to deepen you path and daily life regardless of whether you are meeting pain or pleasure, happiness or sorrow.
So in the end, it is not a choice between maintaining your buddhist faith and living a normal college life. Every day you can discover anew the place in which those two dynamics meet, and then live from that place.
Namaste, my friend. :) Best of luck in your upcoming college career.
