Find a happy medium between arrogance and desperation, cleanliness and too much cologne, obnoxious behavior and being passive, too revealing and not letting anyone in, etc. I think when we get nervous we fall to one end of the spectrum or the other. Relax, and I know people say “be yourself” a lot, but it’s a sure fire way to be vulnerable without being pathetic and outgoing without being overpowering. Don’t think about what to say to impress a woman- at all. Think of what you would say if she was just some dude, but a pretty dude who deserves respect.
Where to look- local concerts in small venues, the library, church?, volunteer location, anywhere you shop, book stores, coffee shops, etc. I think the best chances for exposure is a small establishment with a friendly atmosphere.
Also, as mentioned above by several gentle viewers, it will come naturally if you don’t “hunt” for a mate.
I don’t really know what I’m talking about. Do what makes you comfortable. And just don’t take advice from this guy.
