Take the things that worked well for you and make them your own. Mold them to how you study Japanese so that you can study Japanese even more effectively. Once those become ingrained into you and how you do things, you can always come back to add a few more. What’s important is that you tried a lot of strategies and figured out what worked well for you.
I believe that if you take a lot of these strategies to heart, you can really, really cut down the amount of time to fluency. It’s never going to be easy, but there’s so much you can do to make your studies more effective, so I hope I helped you to do that. You’ll always have to study hard and work hard, but you knew that from the beginning right? Keep at it, and hit me up if I can ever be of any help.
