Odds of Hanging On
Odds of making a long-term living from your talents are very high. Governments and businesses always need gifted interpreters and translators.
Just make sure that you stay sharp in whatever language you're using. Big mistakes aren't the easiest to make, but just one could totally ruin your chances of ever interpreting for important people again. Forget never working for the Malaysian prime minister...you might miss out on your chances of meeting Bono.
