7 English abilities

To understand why you have trouble expressing yourself in English, let's look at what fluency really means...

what you never learn in school is that fluency is a group of 7 essential habits and abilities including:

The ability to speak without hesitation and at lenght even about unfamiliar topics.

The ability to use natural conversational words and expressions like slangs and idioms.

and the ability to speak with confidence.

These habits individually - and your fluency overall - can be visualized on what I call an English Fluency Profile.

The English Fluency Profile of a native English speaker is filled completely Native English speakers have a strong ability to communicate, using both formal and conversational language confidently, correctly and automatically, and the easily understand other native speakers, because they learn everything in English as a complete system. 

A tipically English language learnenr, by contrast, has poorly-developed individual habits and very weak overall fluency because they receive an incomplete language education that does not prepare them for real conversations.
