TTBOMK, there are 3 things which change-the-rules, significantly.
Pimsleur. Get the Pimsleur app, get the all-languages subscription, & do 1 session per day.
Flashcards, or Anki, to get the visual imprinted into your automatic-mind, for any language you are trying to learn
Later..
Tandem, where you find a speech-learning partner, you help other people learn your languages better, other people help you learn your target-language better.
Begin with Pimsleur & with some yt videos.
( they have no Sanskrit, which is the one I want, unfortunately )
