I see this post as something motivational around public writing or public speaking.

It's true that the more you are afraid of expressing yourself, the worse your "performance" is going to be.

On general work level it's different.

There the trust needs to be balanced.

People should feel free to express themselves, but also that they need to meet some certain standards of quality at work.

Otherwise we may tend to relax too much and become sloppy in certain areas.
