I think the big mistake in schools is trying to teach children anything, and by using fear as the basic motivation. Fear of getting failing grades, fear of not staying with your class, etc. Interest can produce learning on a scale compared to fear as a nuclear explosion to a firecracker.

Among a great many other things that chess teaches you is to control the initial excitement you feel when you see something that looks good. It trains you to think before grabbing and to think just as objectively when you're in trouble.

It takes more discipline than you might imagine to think, even for thirty seconds, in the noisy, confusing, high-pressure atmosphere of a film set. But a few seconds' thought can often prevent a serious mistake being made about something that looks good at first glance.

It's crazy how you can get yourself in a mess sometimes and not even be able to think about it with any sense and yet not be able to think about anything else.
