You have heard of the idea that their are seven deadly sins. They are meant to convey a warning and they are countered by seven virtues. Things you should avoid and things you should focus on.
In Business, there may be be 7 deadly sins, but in my experience, there is only one fatal flaw. That flaw is confusing kindness with weakness.
For people who confuse kindness with weakness, their fate seems to have been cast - it never ends well. Consider this story. Enjoy.
