The Disappointment Frontier
theengineeringmanager.com"Disappointment is a fact of life. But maybe we can get better at managing it."
Great quote, and even greater write up.
See also "being less wrong" about stuff. Particularly in a business context.
The idea that a leader (or just a group of people) can have some ability to hit the jackpot straight out, or to know the one true way of doing anything fully-formed, seems to me to be the root cause of disappointment.
