Memorizing (through practice) standard phrases
I just watched an interesting video on the value of practicing standard phrases to the point of memorization. He quoted a finding that around half of what we produce in conversation is not constructed on the spot but is recalled from our store of stock conversation. We know (and use) this technique for greetings, weather comments, questions about cafes, and so on, but the video suggests going further: develop some set paragraphs — where you're from, what you do, your favorite things (books, movies, foods, hobbies, etc.) — that go into some detail. Pick things that are likely to come up in conversation. Then practice those paragraphs until you have memorized and can speak them fluently.
The idea is to build up your stock of set useful phrases so that you can recall and speak them without hesitation — without having to think about them — just as you speak in your native tongue.
Check out the video. It makes sense.
