You don’t need perfect grammar to be understood in a new language. You need to keep talking.

Fluency gets built out of hundreds of imperfect sentences, not out of waiting until the grammar is right. People handle wrong tenses and missing articles without much trouble; what nobody can work with is silence. The learners who get good are not the careful ones, they are the ones who kept talking while they were still bad at it.

Say the clumsy version out loud today instead of rehearsing it in your head. Let yourself be corrected, then carry on without apologizing for the mistake. Three real conversations will do more for you than an hour of worksheets.
