It is true that if you like your job you will always be happy. Teaching is ok, depending on where you teach. Teaching is China is not a vocation or career though, anyone who thinks so is deluding themselves. Better not to teach or work in China if you are a foreigner, it's ok just to live there and have a good time though, that's about it. For the older guys it is good if you are semi-retired or retired, I think that Silverboy poster said that once also, in that instance I must agree with him.
