difficultly of learning new language
I would like to share how I learned English as a Japanese speaker when I was just a beginner.
When I did not understand any English, I tried to speak one specific person every single day and I took notes when I did not know any vocabulary and ask the person to stop the conversation.
If you are shy, it is hard to improve to learn a new language.
If you love the new language (which is English for me), it is better to demonstrate how much you love the language and wanting to understand the language.
That is how I learned!
