What do you, a s professional translator, do to develop your skills in your target and source languages?

I will start by saying that as an English<>Arabic translator, I'm constantly working on my Arabic grammar and structure by reading books and practicing through written exercises to eliminate errors as much as possible when translating into Arabic. As for the English language, I mostly read all kinds of books and I frequently use www.vocabulary.com to keep my vocabulary bank constantly growing.My work as an bilingual editor also helps.

Thanks for the invite,

Simply stated: Developing any skills is attained by practicing such skills. The language skills can be developed through more practice of these skills by different means.
