How do you learn new word/phrase?

Soon after listening to British English, I've been fond of learning English.
For me, talk or narration in English sound like music or poem whatever the theme is.

I don't know why. But I've been quite enthusiastic about learning English.

Apart from my enthusiasm, I'd like to ask tadokists the question in the title.

Sadly, my approach to learning English hasn't been so helpful that I've changed the way of learning it a few times, which haven't worked either.

Why can I use certain words or phrases very easily, while it's so difficult for me to use other words or phrases?

What do you think?

Hi, fauree1845-san. This is Michael.

〉Soon after listening to British English, I've been fond of learning English.

Recently, I am often listening to BBC, the English radio news.
I used to learn American English for a long time like most Japanese, but British English gave me a new light of English.

〉For me, talk or narration in English sound like music or poem whatever the theme is.

Oh yes, I remenber that you're a person in music field!
I think it will be so beautiful to hear English like music.
(Unfortunately, I am a scientific person...)

I have one method from my experiences.
(This might not be good for you, please receive this as just an reference.)
When I was practicing for the speaking test of TOEIC, I often tried to express the every situation I looked.
For example, "I am walking on the sidewalk. There are several cars in the street. A woman is walking in front of me. She is carrying two bags. One is white and the other is flower printed. She has a pony tail..." and so on.
Sometime, I can't find the suitable word or phrase.
In that case, I searched them afterwards and repeated them lots of times in following days.

Actually, I think that you don't need to remember every phrases or words that you learned.
Of cource, you should read and understand them.
But you would better to keep and use SOME of them that you think they are REALLY USEFEL TO YOU!

In short,
to select some words you can usually use, and
to use the words as possible as you can in short period,
seem to be important!

How about this way?

Hi. Thank you for your reply.

Though I can't write about the second half of it, I think your advice sounds nice and useful to me so I'd like to try something.

〉Recently, I am often listening to BBC, the English radio news.

Oh, do you? In fact, I've tried it a few times but I couldn't.

〉I used to learn American English for a long time like most Japanese, but British English gave me a new light of English.

I know what you mean. That sort of experiense has made you deepen your understanding about English or widen your interest, hasn't it?

This following message is the one about the second half of your reply：

Reading your message, I think I should decide which words or phrases are really useful to me.

I can't remember most of them but I can use some of them, which are useful or practical.

It seems that building up your vocabulary should be done little by little.

You've changed my fixed image of using English words in good way.

Thank you.
