How do I learn Mandarin??

I’m so tired of every series I love being across the sea. The tariffs in the US is eating me alive. It’d be cheaper atp to just learn mandarin and then fly across the sea to buy merch of my favorite series.
PLLEEASE, I’m on my knees. I know you guys are insanely talented and are able to read the original raws of stories. What’s the best way I can tackle this??
