This makes me happier(It makes me happy that I/I find it uplifting that I) speak the second most difficult language in the world. (Arabic العربية) :)))

Cool list.  How did you decide which was most difficult?  I went to school with kids from Chinese family and many of them studied Mandarin.  It is undoubtedly a very difficult language to learn.  I looked briefly into learning Arabic once because I love the food and culture.  I quickly realized that it was going to take a lot of my time and energy because it's not simple to pick up.

The correction I made is a suggestion.  Your original sentence is mostly correct however, the suggestion would make you appear fluent.  Let me know if you have any questions about the correction.
