He who knows no hardships will know no hardihood. He who faces no calamity will need no courage. Mysterious though it is, the characteristics in human nature which we love best grow in a soil with a strong mixture of troubles.
No horse gets anywhere until he is harnessed. No stream or gas drives anything until it is confined. No Niagara is ever turned into light and power until it is tunneled. No life ever grows great until it is focused, dedicated, disciplined.
