If you are translating your communication into English, your English will not sound like English and more so you will always find yourself stuck. You will not be able to complete your statements. There will always some expression that you cannot translate word-to-word into English.
Start thinking in English!
How to do this?
Well! The solution to this problem is simple, but the implementation is time consuming. It takes practice to think in a language you are not familiar with.
Here's how you can do this:
There are 4 categories of communication: [Reading + Writing] and [Listening + Speaking]
First read and listen:
The human brain is a vast network of neurons that stores information. But for an information to stay in the brain, the network should be linked properly. Consider it like a series of compartments (something like thoughts and expressions linked together) in which information is stored. So if you want to store information, you have to first create compartments so that information can then reside in it. This creation of compartment happens with time through reading and listening. The more you read and listen, the bigger the network of language faculty becomes.
Second writing and speaking becomes easier and comes naturally to a person with a nicely developed network of compartments of language faculty.
