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.
To some extent you either have excellent writing ability and expression or you don’t.
But it’s also a skill you can hone and improve with experience and application.
