I'm thinking about learning Russian, apparently Korean and Russian are two of the easiest languages, but the big problem is that you need to learn an entire new alphabet.
Although, I think I learned the English alphabet in less than half an hour, whereas I spent an hour learning the Russian alphabet and still mess up too frequently.
Actually, I think I'll learn Korean, after the first Asian language Chinese and Japanese will be easier, and after I'm used to getting down new alphabets I'll do Russian, then use my knowledge of Cyrillic alphabet to learn Greek, then I'll go onward with my knowledge of so many alphabets to learn Hindi and Hebrew, then I'll move onto Arabic! Then once I know all of the root languages along with the fact I speak some broken French and Spanish to learn Latin, then with all of the Romance languages I know I'll learn Italian and Portuguese! Then since I'll know most of the root languages I'll do every Germanic language, then in coralation with Germanic languages and Russian I'll learn all of the Slavic languages!
Brilliant!
I think I covered each language there.
