Many of my EFL students think that you have to participate in some type of language program in order to be successful speaking English. It's also a common misconception among adults that you have to spend hundreds to learn a language, and the money spent on language holidays in Europe is proof of that.
This presentation (originally in German) is my attempt to inspire more autodidactic learning, specifically regarding English.
I wrote more about it on my German/English blog http://bzzlingua.com/language/en/2017/10/14/the-problem-with-language-courses/
This is a free presentation designed to educate and encourage! Please feel free to share!
