Do We Need a Mentor?

One of the most famous cases of this in recent times is a fellow named Ben Underwood. He was diagnosed with retinal cancer at the age of two and had to have his eyes removed. And then he learned with the help of a mentor to detect the location of objects by making clicking noises with his tongue. These are, you know, using dynamic quote unquote silent objects. So we could all learn to practice that location. Is there a YouTube video? Can I learn it?
