It all just boils down to talk to everyone, have fun, don't be too invested/needy, be the best version of yourself, etc.

Maybe it's because I'm in a relationship now, but all of the advice can just be condensed like this, no? Aside from funny lines to say, I just don't understand how you can teach someone to become more suave in dating. I'm far from Casanova since I failed A LOT more than I think I succeeded so maybe I just don't see it.

I had my share of successes with girls I found attractive but I just don't understand how you can teach someone this stuff aside from the basic advice above. Every time I used that advice, I saw results. I just think it more depends on being social and putting yourself out there as opposed to "say this, then she'll say this..." etc.
