The True Value of Criticism 

I think Seth Godin puts it best in his latest post “What are professional reviews for?“

All a long way of saying that if you make something that people are likely to criticize, pay careful attention to which critics you listen to. They probably don’t view the world the way you do, and worse, the way your fans do.
Reading criticism just to ruin your day is a waste of your talent.

Certainly you can replace “reading” with “listening”, which is what we as photographers often do.

My experience has been that we can be a lot more careful about who we listen to.
