I have only one concern about this article.

Isn't it better to develop an analytical skill that helps you to decide whether to act on criticism or to ignore it, instead of learning to totally ignore it. I've learnt that sometimes criticism definitely take your confidence away but sometimes it helps you to improve the quality of work or one can say helps you to right your wrong. You just need to learn to distinguish between positive and negative criticism.

For rest of the article, "Bravo" and "Thumbs up" as a lot of people around the world are still fighting against this problem/issue.

Keep up good work.
