Culture is a mass hallucination, and when you step outside the mass hallucination you see it for what it's worth.
The pessimist complains about the wind;
the optimist expects it to change;
the realist adjusts the sails.
William Arthur Ward
Experience is not what happens to you;
it's what you do with what happens to you.
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.
