The battle of life is, in most cases, fought uphill; and to win it without a struggle were perhaps to win it without honor. If there were no difficulties there would be no success; if there were nothing to struggle for, there would be nothing to be achieved.

Wisdom and understanding can only become the possession of individual men by travelling the old road of observation, attention, perseverance, and industry.
