I have found that getting my writing corrected is very helpful. I read the corrected versions several times. But I wonder if I should reread them until I am confident that if I have to speak to someone in real life about the same topic unexpectedly, I would be able to express my ideas.
Do you rewrite your corrected notebook entries?
How often do you read them?
Or do you move on to writing the next topic?
Have you ever found that having written about a topic and memorizing what you wrote helped you in a conversation in the foreign language?
I also recommend reading as much as possible and exposing yourself to the language as often as you can... Watching movies, listening to music (with the lyrics) and, of course, conversation :)
I promise you that even if you make mistakes no-one will laugh at you. My opinion is that the purpose of learning a language is to communicate, so even if sometimes you're not "perfect" it shouldn't stop you from talking!
