Reflection:

Knowledge is flour, but wisdom is bread.
~ Austin O’Malley (1858-1932)

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.
~ Isaac Asimov, (1920-1992)

By three methods we may learn wisdom: first, by reflection, which is noblest; second, by imitation, which is easiest; and third by experience, which is the bitterest.
~ Kong Qiu (551-479 bc, otherwise known as Confucius)

Wisdom is oftentimes nearer when we stoop than when we soar.
~ William Wordsworth, 19th century English poet

Because sometimes things happen to people and they’re not equipped to deal with them.
~ Suzanne Collins, from Catching Fire (The Hunger Games, Book 2)
