Never ascribe to malice that which is adequately explained by incompetence.
Things may come to those who wait, but only the things left by those who hustle.

Large skepticism leads to large understanding. Small skepticism leads to small understanding. No skepticism leads to no understanding.
Turn your face to the sun and the shadows fall behind you.
Better to remain silent and be thought a fool than to speak out and remove all doubt.
