Wonderful answer from Amany, I think I would probably be a little bit more direct telling them that learning the language, even if they don't intially like it, will open up many different career paths for them and explain that the advantages far outweigh the disadvantages. There are times when you have to weild the stick rather than dangle the carrot and I would say to them "get over yourselves, it's obviously something new which you are wary of and is taking you out of your comfort zone, it's now time to grow up and grasp this opportunity to better yourself".
