How the fuck did this article receive so many points? Burned out working at a bank? Huh? Getting a job because of her boyfriend? What's the moral of the story?
Most of the world makes decisions based on emotions and egos. If you only understand the world in terms of logic then you will fail to make progress with the people that only operate with their emotions. You will pay the price, not them. I would argue it's better to understand the reality that some people only operate in logic, others in emotions and deal with each person at their own level.
Assuming everyone keeps their word and follows logic will leave you at 4AM alone in Berlin with nothing more than tube socks and a bag of vomit.
