There is one challenging task faced now-a-days is communication. Unless you can communicate well your job fields would be restricted to certain areas, it is now mostly mandatory that you have to know atleast more than two languages to call yourself a good communicator. Knowing foreign languages like Spanish, French will increase your chances of selection when you are applying in Foreign companies. They provide higher salary packages to those who works as a Moderator. And yes in genuine cases you can work as a guide also if you having interest in tourism.
Hope it works!! Good luck!!
