I don't know that I have a strategy per se, but just things I've learned by trial and error. 1. Forget Duolingo 2. Pursue comprehensible input in context (there are hundreds of ways to do this, you have to find your own way). Polyglots like Steve Kaufmann and Alexander Arguelles have a few recommendations if you google them. 3. Also, try not to learn words. Learn phrases in context. 4. Ankify phrases that just won't stick. 5. Practice speaking and writing from the get go. 6. Leverage languages you already know to help you learn new languages (e.g. if you already know a Romance language, learning another is easier. Japanese unfortunately is a language isolate, but folks who know Chinese characters are able to pick up the written language faster, and folks who know a language with a similar grammar like Korean are able to pickup the grammatical structures faster -- finding those connections early give you a superstructure to map new ideas to). Consistency is key, and even the very best language learners take about a year to become reasonably familiar with a new language. Disbelieve anything that promises you fluency in 3 months (even Spanish speakers need more than 3 months to be fluent in Portuguese, a closely related language).
