How do I learn Chinese fastest and most effectively

CEO of Mid Curve Capital. Building @daosdotworld

immerse yourself in the culture. 

watch chinese movies. no subtitles first. see how much you understand by yourself. then with subtitles. take notes. 

chinese music. books. spend a year living in china or with chinese people. 

your only form of communication should be the language.

I see, I'm trying to learn it the only 2 things I'm able to recall at the right moment is xiexie and lalala
