A good way to motivate people?

I’ve encountered ‘teachers’ like this.

They’re fascinating creatures and they probably get some results from people who respond well to bullying, but I find they cause more damage than good.

Constant fear is not a good state for creativity, generally you get more of what you focus on, and it’s better to guide people to where they should go, not where they shouldn’t. If I tell you to not think of pink elephants… there’s only one thing you’ll be thinking about.

I’m glad someone made a film about these enigmatic people, I don’t like them but I am fascinated by them, and this was a superb portrait of one.

No. This movie is ridiculous. Abusing students isn't teaching. I guarantee Buddy Rich did not become a great drummer by being treated this way when he was young.
