This doesn't work. I mean, it seems to work for you because you travel a lot or live somewhere where a lot of outdoor hobbies are possible.
For nerdy men, if you're not careful about hobbies you're going to pick some where you will literally never meet a woman into it, or else only strange or highly autistic ones who aren't good for you, and this isn't always obvious ahead of time.
I don't mean anything stereotypical about this either. Like "women aren't into video games or anime" isn't true, but they're not into it the way you might be into it. (In my experience they're healthier about it and like creating/producing things themselves, whereas men like complaining about them online. But this part is a bit stereotypical.)
You do need to know what women who are your type are into, and you need to genuinely be that kind of person or at least be able to appreciate it.
