food (more like a feast) for thought.

If you have built castles in the air, your work need not be lost; that is where they should be. Now put foundations under them.

The surface of the earth is soft and impressible by the feet of men; and so with the paths which the mind travels.

Nay, be a Columbus to whole new continents and worlds within you, opening new channels, not of trade, but of thought. Every man is the lord of a realm beside which the earthly empire of the Czar is but a petty state, a hummock left by the ice.
