I like the effort! It is more that half of the battle when learning a new language as an adult. What really helped me: Create your own custom Anki deck. Literally, start from zero. Each time you try-and-fail (or think of something that you don't know how to say), write a note to yourself in English/broken German with the sentence/idea that failed. At home, use a translate tool (LLM/Google/whatever) to build the correct German sentence. Next, add it to your Anki deck. Personally, I only add full sentences, never just vocab, because it adds more natural context. Only add real stuff that you will use. On the first day, you have an Anki deck with one card. If you are really motivated, try to add one card per day, but just 1-2 cards per week will quickly improve the deck. Since the deck is so damn small, you can blow through it in five minutes while riding the S-Bahn/U-Bahn trains. And, every single sentence is useful to you. Bonus: Ask a native German speaker about some of your Anki deck sentences. They will probably love to talk to you about the German language because you will be showing your commitment.
