Translation is a tough job. Some translators have to deal with a range of 1,500 to 2,000 words in one working day. During peak season or when you have too much on your plate, you might have to translate 3,000 to 5,000 words a day.
Working from morning until midnight is necessary, when you are dealing with a big volume. Some writers might think that working non-stop without rest is the best way to cope. I beg to differ though. The best way to cope with hectic work is to be physically active. I always make sure I swim several times a week to maintain my stamina.
When I feel not energetic enough for work, a swim for 60 to 90 minutes is the best way to become more productive the next day. A long walk, a jog at a park and doing chores at home are also very good choices to keep ourselves physically active.
