When learning a new language, you will make mistakes. Those who see them as a chance to learn, learn, those who see them as failures, don’t.
I have found, in my own language journey, that if I look at my mistakes in a different way I learn more. I used to feel very upset if I couldn’t memorize the entire vocabulary list of the week…but now I know that language is more fluid and less strict. You learn, little by little, until one day, you look back…and see how far you have come!
