The moment a leader allows himself to become the primary reality people worry about, rather than reality being the primary reality, you have a recipe for mediocrity, or worse.

core values are essential for enduring greatness, but it doesn’t seem to matter what those core values are. The point is not what core values you have, but that you have core values at all, that you know what they are, that you build them explicitly into the organization, and that you preserve them over time.

What drives your economic engine. All the good-to-great companies attained piercing insight into how to most effectively generate sustained and robust cash flow and profitability. In particular, they discovered the single denominator — profit per x — that had the greatest impact on their economics.

It is the lesson from the mistake that makes it valuable, not the mistake itself.

What separates people is not the presence or absence of difficulty, but how they deal with the inevitable difficulties of life.

Paradox: You must maintain unwavering faith that you can and will prevail in the end, regardless of the difficulties, AND at the same time have the discipline to confront the most brutal facts of your current reality,

Much of the answer to the question of “good to great” lies in the discipline to do whatever it takes to become the best within carefully selected arenas and then to seek continual improvement from there. It’s really just that simple. And it’s really just that difficult.

Indeed, one of the crucial elements in taking a company from good to great is somewhat paradoxical. You need executives, on the one hand, who argue and debate — sometimes violently — in pursuit of the best answers, yet, on the other hand, who unify fully behind a decision, regardless of parochial interests.

Certainly, we always need to search for new ideas and solutions — invention and discovery move humankind forward — but the biggest problems facing organizations today stem not from a dearth of new management ideas (we’re inundated with them), but primarily from a lack of understanding the basic fundamentals and, most problematic, a failure to consistently apply those fundamentals

Our study clearly shows that a company does not need to be in a great industry to become a great company. Each good-to-great company built a fabulous economic engine, regardless of the industry. They were able to do this because they attained profound insights into their economics.
