In person. Problem is figuring out where they are.
Venue selection is very important for both daygame and nightgame approaching.
Relocation is always the best choice for someone who can't find either:
A. Friends (Socialzing)
B. Women.
C. Work.
People do not realize how important it is to actually change the location you live in. It could potentially expedite your potential to unlimited heights.
Not only work wise, but also socially and romantic wise.
Relocation has a mixed record in solving dating problems. Relocation has a better track record in improving the other 2 parts of life that you mention: friends and work.
The success of relocation depends upon a man's goals in dating and some of his other personal attributes in the areas of looks, money, status, and personality.
Relocation tends to weaken social circles. When men are looking for an extended relationships (1-4 years or more), the best bet for getting that with the least amount of grief and frustration is through a social circle introduction. Getting any sort of relationship without a social circle depends more upon superficialities.
The men I have seen play social circle game the best are men who rarely ever (if ever) move. These are men who lived in the same area for the entirety of their childhoods and then stayed in that same area as adults. At most, they went away to a regional college/university within 3-5 hours of driving of their childhood hometown.
In order to make the life path I described above a reality, a man is dependent upon his parents to keep him geographically fixed until age 18. Additionally, during childhood, the male must be at least ordinary and not a social reject during his K-12 years.
When I was online dating in the 2010s in one of the biggest metro areas in the USA (Dallas - Fort Worth), I had an observation about the pool of online daters using swipe apps. Almost all the women that I met from online dating websites (pre-Tinder's launch in 2012) and then swipe apps were adult transplants to Dallas. They had to use online dating because they didn't have strong social circles in Dallas. It was rare for me to meet someone off of a dating website or app who grew up in the Dallas - Fort Worth area. The women who grew up in Dallas - Fort Worth usually had strong enough social circles that they didn't need to use apps to meet men. They found their longer term relationships from their social circles for the most part. In Dallas, almost all of the swipe app daters (both male and female) arrived in Dallas as adults somewhere in their 20s or beyond.
Men who lack social circles need to end up either approaching strangers, swiping on apps, or sending DMs to strangers on social media. All of those paths are more difficult and less sustainable paths for extended relationships of any kind. All of those paths are more dependent on male superficialities to initially attract a woman. A man will need better looks, more money, or a more dynamic personality to compensate for the lack of a social circle making the introduction and vouching for the man. Relocations reduce the probability that these social circles are in place.
I believe my multiple childhood and early adulthood relocations affected how I was able to develop relationships.
It is worth noting that many men who get social circle girlfriends tend to retain those girlfriends for a long time and often beyond the useful life of the relationship. A lot of the social circle girlfriend guys are beta males and beta males operate from a scarcity mindset. It's common to see a 10 year+ relationship from social circle which does lead to a marriage proposal.
For men with social circles, the problem with the social circle method eventually becomes sustainability as social circles get pissed at men who continually exchange girlfriends, even if the relationships are semi-long (1-4 years). The behavior described in the last sentence is serial monogamy, so it is accurate to say that social circles get pissed off at serial monogamists. It is important to remember that social circles generally have a blue pill viewpoint on romantic relationships. A man might be able to pull 2 LTRs from a social circle without marrying one. After 2 instances, he will have typically bled the social circle dry. Then again, a lot of the beta males who use social circle game aren't interested in serial monogamy and believe in the idea of a sustainable, happier marriage.
