I have learned, over the course of five decades, French, German, Sesotho, and Japanese, with at least some immersion for all of them. Outside of being immersed in the language, Language Transfer (which I'm currently using to learn Spanish) is easily the best method I have ever used. It relies mainly on recognizing patterns, rather than memorization, which is right up my alley. Maybe others do better with memorization? It's also free, and very convenient (lessons are on YouTube, SoundCloud, downloaded MP3 files, or Android/iOS app). I'm a Patreon supporter, because I believe in it.
