Thank you for your question. I would say that it is the best to do it right away. You can start with writing down simple sentences like “I drink tea in the morning”. Try to describe your day with the words you already know. Look up up up to 10 new words that you really need to know to describe your day in a better way (verbs and nouns). Feel free to write the story of your day here in the comment section. I would love to see that!
