What is a weed? A plant whose virtues have never been discovered.

The unstable estimates of men crowd to him whose mind is filled with a truth, as the heaped waves of the Atlantic follow the moon.

Guard your own spare moments. They are like uncut diamonds.

Your work should be in praise of what you love.
