I studied it briefly when I was 12, but it never got any farther than learning all the hira and kata, and of course by age 14 I completely forgot. Didn't pick back up on it until I was 18. I'm 20 now and pretty impressed with how quickly I've been able to take to the language. I'm not bragging or anything, I'm still at a pretty basic level, but my comprehension skills are good. I can speak pretty well. Still need a whole lot of kanji work.
What's helped me is having a Japanese best friend. Also, I wasn't really weeby at all before so I kind of had to force myself to immerse in things like Japanese music and anime. I've always read manga, but I hated anime. It's not a good study tool but it does help you out in a sense that it makes you feel good when you can comprehend what they're saying more and more. A motivator so to speak.
I can't say I've been a diligent student either. I studied pretty lightly, but my first trip to Japan immediately improved my skills. I've been 3 times total, each for a few months.
As far as study tools go, it's probably best to check out j vloggers, they often have decent videos on how they learned and you can kind of meet half way on what works best for you. I don't have any interesting information since I just had the advantage of having a Japanese person present in my everyday life.
