The hours of folly are measured by the clock, but of wisdom: no clock can measure.

The challenge of leadership is to be strong, but not rude; be kind, but not weak; be bold, but not bully; be thoughtful, but not lazy; be humble, but not timid; be proud, but not arrogant; have humor, but without folly.

You can't connect the dots looking forward; you can only connect them looking backwards.
