Yes. 30-40 mght work. I'm glad you have hobbies. I like solitary hobbies too and study a lot on my own. But when my family insult me for not having as many friends as they do, that is the only time I actually feel lonely.

I really hope you find a nice girlfriend soon. You will probably have a better chance with the nerdy type because they will appreciate things like your language skills. Do you know any places to meet more intellectual people?

Maybe you can do your studying at libraries or cafes. I had a stranger ask me out at a library once but I said no because I don't go out with complete strangers. If a girl sees you several times in the same place, and maybe say hi casually, they are more likely to feel comfortable going on a date with you eventually.
