I intend to be fluent in English.

There is a lot of English conversation at work. A meeting for employee development is held every Monday. There, we just use English.

What needs to be developed over the next two weeks is stated in English by the team leader. But because I can't understand what he's saying, every Monday I feel apprehensive and stressed. I sincerely hope I can understand English.
