Should i learn Russian or Portuguese?

I can already speak 4 languages and i want to learn one more. I really want to learn either russian or portuguese. Portuguese is a really beautiful language and brazil and portugal are two very beautiful countries with lively cultures. I also know that portuguese would be a lot easier than russian. Russia is not as beautiful a country, but the russian culture is still fascinating as well as russian history and literature. Can you help me decide which language I should choose.

I've become interested in the Russian Culture and would love to learn the language/type it. I know it would be very difficult but I am willing to learn! Please help! Thank you!

What is the best way to learn about Russian culture and language? I have several Russian friends, but I want to know more and more quickly since they're all gone for the semester/graduated.
