I haven't been watching TED talks for a while. No idea how that happened! I enjoyed a few shorter ones earlier today. Of those, I would like to share How to learn any language in six months by Chris Lonsdale. In addition, you can find a transcript of the 5 principles and 7 actions that he presents below.

5 principles

1. Focus on language content that is relevant to you
2. Use your new language as a tool to communicate from day 1
3. When you first understand the message you will unconsciously acquire the language
4. Physiological training
5. Psychological state matters

7 actions

1. Listen a lot
2. Focus on getting the meaning first (before the words)
3. Start mixing
4. Focus on the core
5. Get a language parent
6. Copy the face
7. "Direct connect" to mental images
