You don't have to be a player, but begin playing/sparing. Try to date. Try to make people find you attractive.

I didn't date much in my life, as I've always been a serial monogamist, but I enjoyed The Game. It's as an easy to read narrative about how some people play the game. In general, there's a psychology to dating and it's important to learn how women think about men. The pickup artist stuff is like a highly transmissible, ELI5 crash course to dating psychology. But, it can go much deeper and in its ethical forms it's like a non-PC, dating-specific version of Carnegie's How to Win Friends and Influence People.
