Sir Thomas Fowell Buxton has said, “The longer I live, the more certain I am that the great difference between men, between the feeble and the powerful, the great and the insignificant, is energy—invincible determination—a purpose once fixed, and then death or victory. That quality will do anything that can be done in this world—and no talents, no circumstances, no opportunities, will make a two-legged creature a man without it.”
