Know 2 languages? You are in demand
If you know two languages, that is fantastic news for you because you just increased your earning power.
Speaking multiple languages is a huge asset that many people do not possess. Depending on the language and your region, you could be up for a significant raise, but even if not you are a specialist in a field few probably speak in your locale.
Either way, you are worth more money to any company and you should demand more.
Don’t know a second language, learn one.
I suggest picking an easier language to pick up. Chinese would not be one of them. Spanish is.
But its expensive to learn, right?
Not necessarily, you can pick up some audio book cds on the Internet for pretty cheap and listen to them while you are in your car doing nothing anyways. Its a win-win. You keep your time and learn.
Efficiency and marketability combined in one.
You are becoming more successful.
