I'm interested in your methodology. I was trying to teach myself spanish for about 6 months. After awhile, I could start reading at a very basic level, then I hit a plataeu and is felt like even with 3+ hours of studying everyday my abilities never improved. You seemed to hit a much better much faster than I have so.... teach me your ways.
It probably varies between individuals but I can give you some insight into how it has gone for me.
I did spend 3 months in Guatemala in 2016 where I picked up the absolute basics. A bunch of verbs only in the present indicative, a little bit of the preterite, and the simple future using ir. I didn't learn more because I was conducting research on people who spoke English and most of my free time was spent in bars. If I had the mindset then that I do today, I probably would not have spent so much time in money in those bars, but that was a different life.
Otherwise, I didn't start learning it again until after I finished my graduate thesis last October. So I probably started seriously studying it in November. You have to do it every day, and review all the time. Sometimes I miss a day, but if I'm really busy I do try to at least read a few pages in Spanish, or look up and memorize 5-10 words, or try to think in Spanish throughout the day (even if very simply)...or at least review some of my vocab notes.
What really worked for me was reading about grammatical rules regarding moods and tenses and trying to learn about them from multiple sources (videos, reference books, websites), then trying to understand them when I encountered them in my studies. I often look up vocab whenever I can, write them down, put them on sticky notes or whatever, and review them whenever I can.
Also listening to songs, watching videos, trying to write. Translate books, plays, the news. Then reread them again and again, reinforcing the new words and grammar you've learned.
What helped a bit also was I spent 6 weeks in Mexico in November and December, but a lot of the time people I was with spoke in English. I did learn some though, and a lot of the days there I spent reading about grammar and vocab before reinforcing it throughout the day. I do try to write in Spanish to the person I was visiting down there, and sometimes I skype with them and speak in Spanish but not that much because her English is better than my Spanish (although I'm catching up very fast and maybe one day Spanish will be the easier language for us to speak in).
I don't know what else to say. Consistency, review, variation, and dedication. Get excited about it, know it's something you really want, envision yourself knowing it in the future. For me reading about famous polyglots gets me excited...I read a book by the polyglot Kató Lomb where she describes her methods, which are heavily reading focused, and that really got me excited. Also I often read about Richard Francis Burton, the 19th Century British explorer and linguist who apparently spoke 30 or so languages.
Learning the grammatical basis of the moods (indicative, subjunctive, imperative), tenses (past, future, present, preterit, imperfect, perfect etc etc) has really smoothed the transition into learning French as well, because a lot of those things are the same in French so I do not need to spend the time understanding their function, except for a few minor differences like the preterit only being a literary tense in French. Others seem to ignore grammar and focus on speaking only, that's not really how my mind works nor what I want to do.
So yeah, it's fun, if it weren't fun I would need some kind of practical reason to do it. You need some kind of motivation or goal.
