I think I have done three of four Ted Talks Tuesdays. I will continue to do them. I use them as a mini class to inspire me to learn about something I have great interest. If you have an interest in language learning, I hope they inspire you as well.
Benny the Irish Polyglot gave this great speech on becoming fluent in many languages. Hope you will find it inspiring too.
