English is the king of languages.
>A
French and German have a rich history, strong economy, functioning institutions and culture. I have a soft spot for German because of old games, castles, Warhammer and generally being a window to the world in the 2000s. French is the literature and comics and cartoons (anime was in French back in my days) of my childhood. Japanese is in this tier as the king of the tier B. I am a huge fan of Japanese, French and Italian automotive industries
>B
Spanish and Chinese are business languages, both have interesting history and culture but their territorial areas are far away from me. Chinese seems to be more profitable and there are fewer people who know it, but I have Spain nearby so it evens out. Spanish is also here as a Romance, simpler alternative to French. Norwegian is a language between Danish and Swedish, it is outside the EU, has nature and seems like a good place to drop everything and leave the country. It is here as a simpler alternative to German.
At first there was also Japanese here, but it's so perfectly between tier A and B and has such a significant impact on modern culture that I promoted it higher.
>C
Dutch, Italian, Cantonese are here as alternatives to their language groups but for various reasons they are ranked lower.
Brazilian and Argentinian are here because of my abandoned dream of riding a motorcycle across LatAm from high-fiving penguins in Patagonia to reaching the Amazon. I will never do it, but I will always have a warm place for this dream in my heart
Italian would be higher but it's in this weird spot where it is the second or the third in any category important to me that I can imagine
