The longer I live, the more I am certain 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.
