'The good is the enemy of the great.' - unknown (Voltaire?)
You don't stay in a job unless you are good at it. Good is normal. Most people are good. They aren't great.
Most people don't achieve anything truly remarkable, since good performance is common. Companies with good people are average.
Only companies with great people are exceptional.
The great people deliver 80% of the revenues, 80% of the profits, 80% of the strategy, 80% of the ideas etc. And they know it.
No number of good people can replace a great person. And they know that too.
You only want great people. You don't want good people.
Great people don't enjoy carrying good people. They'll find somewhere which is great.
Don't be a good person. Be great or get out. Find something you are great at.
Don't hire good people. Hire great people.
What are you great at?
