welcome to my tutorial
before i begin- i just want to backtrack a bit

before you begin to learn a language, it's good to have a goal and a motivator. for example, I want to learn conversational Spanish. Why? because I want to travel to Spain. I want to learn basic/intermediate Korean. Why? because I'm tired of reading subtitles on k-dramas

the next thing you need is a time slot. how long do you want to spend learning this language? 3 months? a year? this will ultimately depend on how much you're trying to learn. if you're getting ready to travel somewhere, I'd say 3 months minimum is a good amount of time. you'll only need a basic understanding of the language. if you want to be able to intake media and talk online to people who speak the language, of course you'll need a deeper understanding and 1 year would be a more tangible goal. maybe even 2 or 3, depending on how serious you are.

its highly unlikely that you'll be fluent by the end of these 3 to 36 months. the time slot goes hand in hand with the goal and motivator. i want to be able to speak conversational Spanish in 3 months when i go to spain. i want to have a basic/intermediate understanding of Korean in a year from now so im able to watch k-dramas without subtitles

this will help you stay motivated during the whole learning journey.

the second part of learning a language is actually knowing the levels of language fluency there are.(CEFR) this website explains better than I could. It's really a personal choice, whether you want to use these levels or not. Personally, I use the levels as a way to tell where I'm at in my journey, and what I need to practice on to get more proficient.
