I haven't learned about particles or anything like that yet, but I learned hiragana/katakana a little over a year and a half ago.
I've tried continuing my learning several times since then, but no matter where I start, I always run into something that was "too hard" (like kanji), got frustrated, and quit. Rinse and repeat. Hahaha
I tried reading up on things like particles a few times, too, and I just couldn't wrap my head around how they worked... Especially ones that are used in a similar way to others.
But I think that if I can pulling off learning the kanji, and get some vocabulary, it will be easier to recognize why and when certain particles are used. That all the things I've learned will help "fill in the gaps".
