Do you sometimes hear fluent English speakers and think, Wow! I would have never expressed myself using those words. I wish I could sound like that too! 

Yes, you can already communicate quite well, but you often find yourself using the same vocabulary, and your sentences are not as expressive as you’d like them to be. So you keep practising, but making noticeable progress has become harder.

I can understand how you feel. I was a learner of English and when I got to a higher level, I too struggled to make further progress. It’s absolutely normal, so don’t beat yourself up for this.  

To keep advancing, I used to challenge myself and I think you should do the same. Reading and discussing non-fiction books and creating meaningful personal stories is what you can do to step out of your comfort zone and keep improving.

This is what I can help you with.
