At the beginning of the Chapter, the author Gave a question that: “Have you ever considered the idea that if one person, anywhere, can do something, any other person can learn how to do the same thing? What the effect might that have on your learning and understanding?”

Did it get you to recall something you are familiar with?
Many things were considered as an impossibility until they were achieved, and then they were not a barrier anymore they can be surpassed

The real purpose of the author is just to tell us that language learning is also one area where such barriers have already been removed by quite a few people,

And the example that if all the people in France can speak French then French can’t be that hard really convinced me, I can speak Chinese anyone can learn Chinese and speak it as well as me

Meanwhile What’s even better is that the more you have learned already, the more you can learn easily in the future. For instance, I am a programmer indeed, I have mastered one programing language like PHP or JAVA, and then it’s easy to learn a new programming language C++ or Golang .things are relevant

If you want to achieve something extraordinary in your life, the easiest way will be to find someone who has already done it and then begin to copy what they do — which is called ‘modeling’.

Yes, It’s exactly true, when you model others you can get the real strategies (a whole range of beliefs, ‘tricks of the trade’ and both mental
and emotional strategies) that really worked on you, you can use it to make your process interesting fun, and effective.
