Translation requires the individual to accurately convey the meaning of written words from one language to another. Working as a freelance translator is common. Translators predominantly work with business, technical, legal and scientific written materials.
To be a good translator you must be a very good, and not merely adequate, writer in your target language. You must have a way with words, the ability to write with flair. And you'll likely need to do that across a variety of text styles – promotional and marketing, formal/legal, casual, technical, etc.
