I've used nearly every method to meet women since I entered the mating marketplace as a teen in the late 1990s.
From the early 2000s-early 2010s, I was primarily a nightlife venue type guy. Prior to turning 21, I was going to off campus apartment complexes known for parties while in college. That serve as a precursor to the bars. Once I turned 21, I was going to the bars and doing nightlife venue approaches.
By the early 2010s, I was in my late 20s and had interest in new methods besides nightlife venues. I read Roosh's Day Bang soon after its September 2011 publication date. Day Bang was a transformative book for me and I changed from being a primarily nightlife venue guy to a non-bar approacher guy. Prior to reading Day Bang, I had interest in non-bar approaching, as I had heard about guys meeting women in yoga classes as far back as the mid-2000s. Day Bang gave me the tools necessary to learn how to approach and set up dates in non-bar venues. For 10+ years, I have been a primarily non-bar approacher. There are a lot of different non-bar venues where you can approach. Some are better suited than others to someone's personality and temperament.
I also have experience in other methods of meeting women. I have used both dating websites and dating apps over the years to meet women. I have used DMs on various social platforms over the years. I have participated in co-ed sports leagues. I even tried Meetup.com groups, which were complete shiit. I've done structured singles events.
I never had a social circle that was capable of providing me introductions. There were a couple instances where unattached women entered my social circle many years ago and they were fought over by multiple men in the social circle. The guys even violated Iron Rules of Tomassi to secure relationships with these women. Most social circles have a blue pill ideology towards romantic relationships too.
There are many ways to meet women. Find a way that is good for your needs.
