To say nothing of the "Certifications [OP is] planning to obtain by EOY: GCP, Kubernetes, Google Ads, Salesforce, Quickbooks, aPHRm, HubSpot, CAPM, fb Blueprint, AWS" -
https://www.linkedin.com/in/kevin-de-asis-593876102/I can see that someone who wants to be a professional historian of Scandinavia might want to learn Danish, Norwegian, and Swedish; and a historian of Spain might learn Catalan, Spanish, and Galician at the same time.
At least, those makes a bit more sense to learn together than, say, learning Quechua, Xhosa, and Tamil.
I don't think it will be hard to talk the OP out of this challenging task.
EDIT: I just remembered a friend of mine got a Master's in Classics, which included learning to read (not converse in!) a half-dozen or so languages over a couple of years, including French, German, ancient Greek, Latin, and Sumerian. She spent almost all her time studying, surrounded by dictionaries.
