If you constantly describe your English as “bad” or “terrible

,” or if you say things like “I can’t speak English very well” – you will eventually begin to believe that it is true. These negative thoughts will make you less confident, and your progress in English fluency will be slower. You might even give up completely, because you believe you can’t do it.
The people who are most successful in achieving goals are those who believe they CAN do it and who make the goal part of their identity. Even if your English is not perfect, tell yourself:

“I AM AN ENGLISH SPEAKER. I AM LEARNING TO BE FLUENT, AND I AM MAKING GOOD PROGRESS!”
