Writing clearly and well is not easy. Don't think you can write as easy and fluently as you do in your native language. It takes time, but it is time well spent.

Learning how to write in a foreign language is learning how to write in your own language. You cannot use as many words as you do in Catalan, but thinking of which words you use, how you connect the sentences and which is the structure of your texts will help you to write better both in English and in Catalan. I promise.
