In my opinion the article was extremely good, because it speaks of everything that happens to people when it comes to art, so, theater, movies and concert, everyone needs people who are not ashamed to present themselves in public.
That's why we have to convince people that to stop being ashamed will help them for the rest of their lives with their daily work.
I will not mention any evidence or example but it is easy to see, it happens almost always.
And it is very common to find people like that, it has exactly everywhere you can imagine, especially at school.
