Expertise Is the Key to Success, But Overconfidence Is a Disease

Symptoms of Overconfidence:

• Believing you can solve every problem with a single swipe of your wrist.
• Taking unnecessary risks, because "it's all going to work out."
• Refusing to listen to others, because you're "the expert."

Treatment:

• Admitting you're wrong.
• Listening to others, even when they're wrong.
• Embracing uncertainty, like it's a good thing.
