On the face of it, no, but as you read through the article both sides of the "Yes/ No" coin are argued well...

However, the most telling paragraph of the whole article comes just before the end; where the writer sums up exactly how you should feel when you encounter failure, in whatever form that may be: 

"Don’t beat yourself up about it. Don’t overly introject this as a failure that is a representation of your value and worth as a person. Your life and your career are not defined by this. But do be disappointed. Do be frustrated. Do seek to understand what happened. Do seek to know if you could develop your management and leadership. Do seek to learn from this experience."

Keeping this in mind might just lead you on the road to success.....
