M 20 Looking To Get Back In The Dating Game

So back in high school I had a lot of luck with girls and even into my freshman year of college. After a break up the 2nd semester of my freshman year, I kicked it solo (even eliminating hookups and flirting) just because it felt like it was time to take a long needed break from it all. I'm now a junior at my somewhat smaller(ish) university and I want to get back into the whole flirting, dating, maybe even hooking up thing. It seems a lot has changed since I fell out and my old tactics have become stale or just get me weird looks. So any advice redditors?? I'm straight btw haha.
