Focus on fluency not grammar. When you speak in English, how often do you stop? The more you stop, the less confident you sound and the less comfortable you become. Try the mirror exercise as we talked about in the previous lesson, but challenge yourself to speak without stopping or stammering the entire time. This might mean that your sentences won't be grammatically perfect, and that's okay. If you focus on speaking fluently instead of correctly, I think you will still be understood and you will sound better.
You can feel in the correct grammar and word rules as you'll learn them better. Remember that communication is more important than grammar. Don't worry too much about grammar when speaking Do you get nervous when speaking because you are afraid of making a mistake? Remember that the first goal of speaking English is to communicate. A low grammar is important. It is less important than communication when speaking English.
Here's a simple example. If you say, yesterday, I go to a party on beach. The sentence isn't grammatically correct, but it does successfully communicate your message. And an English speaker will understand you. It's better to say something wrong and still communicate successfully than to say nothing. Also, the grammar of spoken English is more flexible than the grammar of written English.
So don't worry too much about grammar when speaking grammar translation methods and memorization of rules have been standard practice for a very long time. But they are probably not the most effective ways to learn. Some students study English for many years and know all the rules of grammar and sentence structures, but still struggle to communicate properly and hold a conversation in English. So it's important to have a significant amount of time focusing on conversational functional language use a learn in context through interaction with other people.
