Make Money Teaching English in Europe!

I'm amazed at the number of post-university students who come to Europe, thinking they're going to support themselves by teaching English. I think these kids consistently overlook two key facts:

1. The ability to do something is not indicative of the ability to teach it.
   
2. Simple supply and demand. Contrary to what most of these kids believe, teaching English isn't like giving away gold. Or even free sandwiches.
