It's actually pretty great language for self-study once you get to a good enough foundation. It's really endless and there's so many rabbit holes to get stuck in - ancient literary language especially. I'm excited to try and get deeper in to that. My ultimate goal is to be able to read the Big 4 novels confidently.
It's also one of the weird things where motivation has a real snowball effect. The more you know, the more it feels like you can do, the more doors it opens for exploring entirely new areas. It helps that with Chinese there's so much that feels locked up or hidden from normal western view. Want to learn about tea production, culture, and history? Need to learn Chinese. Want to better understand Japanese kanji and history? Need to learn Chinese. Trying to grasp all the distinct geographic dialects and idiosyncrasies is tricky. Also the fact that a quarter of the planet kind of lives and operates on a separate internet, and the FOMO I felt by not being able to understand that.
Anyways, 10/10 definitely recommend. My plan is to keep chugging through and get to HSK 6 studying after my newborn infant arrives in 2 months, though I don't know if I can keep up the 10 hours a week I'm currently managing. I'm also doing elementary Japanese at a way more casual pace with local classes, and my Spanish has disintegrated to barely being usable.
There are so many more helpful tools and communities that exist now than 10-20 years ago, like chrome extensions and better repetition tools, though I still enjoy just handwriting in a notebook a bunch.
