If a language seems hard let's learn one that is easier. For and English speaker that would be Spanish or French (just counting those more international ones and which the bulk of the Anglophone population is familiar with). People prefer what seems easier to them over what seems more complex, from the starting point of their own language(s).
I don't think you should assume things like this. I chose to learn Spanish because the town I like in is 53% White, 46% Latino, and 1% Other, including but not limited to Middle Eastern, Far East Asian, and Indian. 15% of the Latinos only speak Spanish. This means about 7 out of every 100 people, if we can assume every white person speaks English, which probably isn't the case, speak only Spanish. My town, composed of 60,000 people, has roughly 4200 people who speak only Spanish. Obviously, it would not make much sense for me to learn Uzbek, Zulu, or Mongolian.
I personally don't care much about languages that are popular, I'm actually interested in being a scholar of Antiquity and Medieval studies. I have little interest in modern languages, only as the means to read studies about old languages and history.
From what you've said about hard work and being forced to do things that are hard even though you have no interest in them, you want us to be forced learn about YOUR interests, specifically Medieval and Antiquity studies?
