I've become absolutely convinced that the seminal difference between successful companies and mediocre or unsuccessful ones has little, if anything, to do with what they know or how smart they are; it has everything to do with how healthy they are.

A core value is something you're willing to get punished for.

Team members who are not genuinely open with one another about their mistakes and weaknesses make it impossible to build a foundation for trust.

If the CEO's behavior is 95 per cent healthy while the rest of the organization is only 50 per cent sound, it is more effective to focus on that crucial and leveraged 5 per cent that makes up the reminder of the CEO's behavior.

When you know your reason for existence, it should effect the decisions you make.

Success comes only for those groups that overcome the all-too-human behavioral tendencies that corrupt teams and breed dysfunctional politics within them.

Remember teamwork begins by building trust. And the only way to do that is to overcome our need for invulnerability.
