1. Don't try to learn too many words at once. Focus on mastering one word or phrase at a time.
When we start something new we feel so energetic and enthusiastic, similarly when we start learning Korean language we want to learn a lot of things in the starting and to master the language in a shorter time is a goal of every language learner, but somehow we forget that learning is a process that need to go gradually and consistence as it's a lifetime process. You will be learning something new every day in your learning journey so, instead of learning so many things at once try mastering one word or phrase on a daily basis.
2. Don't rely too heavily on Romanization. Try to learn the Korean alphabet (Hangeul) as soon as possible.
In other languages, learning a language starts with learning romanization and then gradually learning their alphabet and words. Some learners try to learn Korean in the same way through romanization. However, that's not the case with Korean language as romanization is very different from the actual pronunciation of the letters, so it's better to learn the Korean alphabet (Hangeul) as soon as possible.
3.Don't be afraid to make mistakes. Nobody is perfect, so don't be too hard on yourself if you make mistakes when speaking.
As a Korean language teacher in LKI, I have seen student struggling with the fear of making mistakes. To avoid that, they don't want to participate in speaking activities as they feel they will make mistakes and it will be embarrassing in front of other students. A language learner should know that your speaking can be better only when you try to speak, when you make mistakes and then you work on those mistakes. So it's advisable not to be afraid to make mistakes as it's a part of learning a language.
4. Be flexible with rules while learning the Korean language.
The best advice anyone can give you about learning Korean language is to be FLEXIBLE with whatever rules you are learning as there are so many rules and exceptions in Korean language and as you will be upgrading to the higher levels, you will realise that they are just different ways of saying the same thing. So just going with the flow and being flexible is the key to learning the Korean language effectively.
5. Don't be too strict with yourself. Learning a language can be hard and it's important to take breaks and have fun while you're studying.
Some learners forget that learning a language is different from studying other subjects like science, maths, business. In language learning, it's not always about concepts. Some things will not make sense to you, but you should accept them as they are. You should not try too hard to understand every single point. Sometimes taking a break is a good choice and then starting with a fresh mind works well. Make sure that learning the Korean language becomes an enjoyable and fun activity instead of becoming stress for you and that's the ideal way of enjoying the process of learning a new language.
