you go to some terrace type place after work and sit there for about 2 hours, like from 6:30 PM to 8:30 PM, then go home, everyday
if you don't have friends, that means you count on strangers inviting you to their table
or sit on a street corner for a few hours every day with cigarettes, like I see some guys around here, doing that seems to attract people so if you have time to waste you can try it
but a truly average guy nowadays won't get anything from that, what he'll do is get status and save money, wait until he's 30 or older and can now be matched with unwanted women in their 30s.
then family or friends will bring some shit tier older woman around and basically set the two up, without much finesse involved.
then a pair of unwanted 30 year olds can have a sad excuse for a relationship where they raise a dog or something.
this is how internet personalities like Konjak or Vee got any action, they didn't pursue or choose or do anything active with social groups, they were matchmaked by friends with older women, after they got money and e-fame.
