I've decided to learn Japanese as a way to reverse the brainrot that being mentally ill for years has given me. So far I'm using a combination of Duolingo and the Human Japanese app, and I'm currently focused on learning hiragana and katakana characters. I also wish to learn Spanish concurrently once I know I've made a habit of studying every day. What are some effective resources that you've used to become fluent in a new language? Especially Spanish and Japanese! :-)
