Is any bilingual person qualified to work as a translator?
All translators are bilingual people, but not all bilingual people are translators. Think, for example, of a marathon runner. He may start off as an amateur who enjoys a 2-4 mile run every other day, but eventually, he will have to train for months, study his sport and hone his skill before he is able to run a marathon. Similarly, it takes careful training and skill for a bilingual person to become a translator.
