This is very short from Seth Godin, so I've reproduced the entirety of the article below:
The worst feedback is indifference
We armor ourselves against the cutting remark, the ad hominem attack, the person who just doesn't like our stuff.
But all of this is the feedback we get when we touch a nerve and are doing work that matters enough to care about.
No, the worst sort of feedback is no feedback at all. That means we've created nothing but banality.
