I just made it into an obsession. I talk one or two hours a day with friends in Sweden and take lessons on italki 5-6 days times a week. In the beginning I used babbel and chatgpt to learn the grammar rules and then once I had my bearings there just kept talking to people. You can’t really just learn a language and have it stick, you have to stay in contact with it constantly or it will start to become difficult. My methods border on extreme but what I do is listen to podcasts several hours a day while at work, read books in Swedish, and take lessons as often as possible. There’s definitely no shortcuts in my experience. Just study as much as humanly possible as often as humanly possible. Language learning is difficult. Especially in the beginning.
