Wisdom is the reward you get for a lifetime of listening when you'd have preferred to talk. - Doug Larson
Knowledge and wisdom, far from being one,
Have ofttimes no connection. Knowledge dwells
In heads replete with thoughts of other men;
Wisdom, in minds attentive to their own.
Knowledge, a rude, unprofitable mass,
The mere materials with which wisdom builds,
Till smoothed, and squared, and fitted to its place,
Does but encumber whom it seems to enrich.
Knowledge is proud that he has learned so much;
Wisdom is humble that he knows no more.
- William Cowper, The Task, 1785
