Never Quit

Don't give up, though the pace seems slow,
you may succeed with another blow.

Success is failure turned inside out,
the silver tint of a cloud of doubt.

And you never can tell how close you are,
it may be near when it seems so far.

So stick to the fight when you're hardest hit,
its when things seem worst - you must not quit.
