How do you try to learn it.
By "actually learn it" I mean picking up a book, using software, going by courses meant to teach you.
But what I've been absorbing has just been mostly reading subtitles and signs with the English version next to it. Sometimes listening, but that depends on the speaker. A Mexican born-and-raised Hispanic tends to be very difficult for me to understand, but their American born and raised counterparts, those who speak Spanish in a way that more resembles English in flow and pauses between words, I can understand them way easier.
I stumbled badly when I took German in college because memorizing lists of words and learning weird rules did not capture my attention.
To me German isn't too bad. Book learning got me through to where I can speak basic conversation level stuff with Germans (and get told my German is very American).
But I easily learned some words and a few short phrases when I was in Japan and India.
Japanese has gotten hard. Not terribly difficult, but hard enough to get frustrated over how they conjugate verbs. I never knew a language could have the conjugated bit be several times longer than the stem of the verb being conjugated. Weak and strong verbs don't exist. And while they may have fewer cases than English and German, it doesn't make it any easier. This one I'm definitely going to have to start watching things like kid shows to help give me a boost in understanding how it goes.
