Entering College with a new mindset

Hey guys,
I just graduated high school and somehow I made it this far (and into a nice college) despite my addiction to Porn and Masturbation.
Honestly, high school didn't go great for me, my excessive addiction to porn and masturbating didn't let me focus, my memory is shit, and I spent most of my time in my locked room. My grades weren't that great, but I think my extra-curriculars helped my get into the college of my choice, but I am here to change this.
This fall, I'll be entering this new phase of my life in the States, 7000 miles away from home and school, I feel like I can be whoever I want, so, I am taking the NoFap challenge to reboot my life, meet new people, and maybe focus on my grades.
It's gonna be a long four years ahead of me, so, it would be great knowing you'll and helping each other achieve our goals!
