To be fluent means to flow. Take a piece of silk and throw it in the air. See how it falls. It falls a different way every time.
Silk flows its own way. No one tells it this way is wrong or this way is right. Each way is new. Because every moment is new. When you speak or write, you just need to do what silk does. Go your own way. Go with the moment.
Silk is always fluent. You can be, too.
