I saw this post on LinkedIN, and it's been shared by Chris Do. A famous Design Director who runs his own design company named Blind. I really like what I read, because it reminded me of many designers IRL and community forums where there are designers who you criticize, they get all defensive and aggressive just because you gave them feedback that you believe will help them. If you can't take criticism, then being a designer isn't for you. That's what I believe.
