I dropped Spanish which was the only language offered during my high school years. I regret it, and now I'm embarrassed to start learning as a uni-aged guy. I want to learn Mandarin because then I would know English and Mandarin which would cover like 50% of the populations speaking abilities.
Basically I just feel like a dumb American and being a Marxist I need to know another language.
Memorizing all the characters I find is the hard part, the grammar is much simpler than English or German, that's for sure
I have no trouble memorizing the digital characters, but holy hell, writing is tough. I pretty much only can write 我，你，用，有 and a couple others from memory, and I practice writing at least a few hours a week.
