Good is the enemy of great.

The kind of commitment I find among the best performers across virtually every field is a single-minded passion for what they do, an unwavering desire for excellence in the way they think and the way they work. Genuine confidence is what launches you out of bed in the morning, and through your day with a spring in your step.

Genius of AND. Embrace both extremes on a number of dimensions at the same time. Instead of choosing a OR B, figure out how to have A AND B-purpose AND profit, continuity AND change, freedom AND responsibility, etc.

I can just let my curiosity wander unleashed.

Just because a company falls doesn't invalidate what we can learn by studying that company when it was at its historical best.

Not every financial company toppled during the 2008 crisis, and some seized the opportunity to take advantage of weaker competitors in the midst of the tumult.

Managing your problems can only make you good, whereas building your opportunities is the only way to become great.
