I’m afraid I can’t tell you the secret formula to successfully learn a language. Everyone who has become fluent in a secondary language has had to go through the same journey. I am fortunate to have German all around me. So what did I do? I soaked my brain every day. I activated all “die Sinne” and kept at it consistently. Remembering words by seeing, listening, reading and reciting. Joining a class, getting a tutor or a tandem partner is a good first step. Then the rest is up to you to apply. Here is my kitchen (the place I actively spend the most time at home). You see what I mean by brain soaking?
Sinne [Sin-neh] Noun
The way in which the body perceives an external stimulus by way of sight, smell, touch, hearing, taste.
