The best way to become fluent in any activity is doing it as much as you can untill you can do it automatically. So, I decided to improve my writing skill in English from tonight.
In my school years I used to be very good in writing. My compositions were excellent both in spelling and content aspects. But when you use your native language and when you are trying to write in second language it's completely different situation.
The main reason why I've started to write every day is my desire to pass exam and to receive FCE (First Certificate in English, Cambridge exam to prove Upper-intermediate level of knowledge). But writing in English is a real pain for me now. But I hope to get the hang of it.)
