I'm a native English speaker as well as a native Spanish speaker. I speak Spanish to my family members most of the time at home. It didn't really take me too much effort to learn it. So I believe having a environment where the target language is spoken is very crucial.
My question is, after making my mind to seriously learn Chinese, the so-called language for the next decades, Is it easier to learn Chinese or to learn Spanish? (I know many people have said Chinese is difficult to learn, but after self-learning it for a few weeks so far, I found it is not as hard as I expected and actually it is interesting to learn though)
