I don't want to sound critical, but it seems as if you are trying to fish from the same spots you've never had any luck with.

I believe when people say to meet people through hobbies, they're typically meaning new hobbies. If you aren't finding any suitable partners within your horizons, looking more often probably isn't going to help. That's a sign that it's probably time to expand your horizons, do things you haven't before, try something you don't have an interest in, be uncomfortable, change your environment.

The world isn't hiding women from you, you are hiding from the women.
