@ehBeth,
I know the recommendation is a wise one. I actually attend quite a few events and meet plenty of people already. In my day-to-day professional life too, I meet plenty of new people. I'm already a member of one of the groups I found at meetup.com (didn't even know earlier that they were on meetup.com). In spite of all this, nothing has really worked out so far. But yeah, there could be a multitude of reasons for that, and it would be difficult for you to guess without knowing me.
Thanks a lot, @ehBeth, @CalamityJane, @Germlat, for the extended conversation.

Having just been refused a date, it's very comforting to have people to talk to.
