Anki cards for like 2000~ words. Childrens books learning videos and texts talking with people in games esp VRchat which is free and doesnt require vr. journaling looking up grammer rules when i noticed it and using some cirriculum books i managed to get ahold of. engage with your interests in the language (talking, reading, etc)

Basically the rule is to engage with the material as much as possible. If you want to speak you have to speak it, even if you suck and its super embarrassing. You just gotta do it. Speaking is a seperate skill to reading and writing and listening. It just requires a little bit of time every day and you can get it. IIRC the US army does a really intensive immersion program when it wants soldiers to learn a language and languages that are "complex" like chinese or japanese require 6 months but other languages require less. IIRC conversational in spanish is just 2-3 months. but thats at the most intense version of this regiment.

BTW if you keep messing up a word, You could spend a lot of time trying to get it and you probably should if its important. But when I was in the word mining phase which is when you are trying to find new words to add to flash cards to study I often found If I was getting a word wrong over and over, I didnt remember it by cramming a ton of study time, I remembered it by encountering it in real life. Usually in a very memorable moment. So make as many memorable moments as possible and have fun

switch all devices to target language ofc but you should get at least to the point of reading childrens books before then. But if you dont understand you wont learn. You need to understand like 85% of a sentence to be able to learn what the last portion is without aid.
