What should I do in my last 1.2 years of college to maximize my experience? What do you wish you had done

I'm currently a junior with a decent internship offer. While it's not overwhelmingly impressive, it's certainly solid, all things considered. At this point, I've disengaged from the typical aspects of college life typical of a finance student: recruitment, the importance of school or bank prestige, and even the perceived status of fraternities or business clubs.

I'm eager to make the most of my remaining year and a few months. Looking back, my biggest regrets in college and life, in general, are succumbing to anxiety and prioritizing work excessively. My anxiety has always been intense, bordering on pathological, yet it doesn't hinder my work. Socially, I'm capable, but I've struggled to build strong friendships, maintaining just a few close ones whom I seldom see. I have numerous "good acquaintances," people I'd talk to for a few minutes at a bar or stop and talk to for 2.5 minutes and say "I'll see you around dawg/bro"

I regret not joining interesting clubs or activities, which I believe are key to forging friendships and finding a community. Now, as an upcoming senior, I feel it might be too late, since most new members will be freshmen and frankly there's not enough time. I'm curious if anyone has advice on navigating the end of college or what they wish they'd done differently.

Despite my regrets and the ways I feel I've negatively impacted my college experience, I acknowledge my efforts to step out of my comfort zone. I've managed to secure a decent internship, studied hard,  had a few interesting experiences, and attend a T25 college, so I try to cut myself some slack.
