Ferdinand Foch

A lost battle is a battle one thinks one has lost.

None but a coward dares to boast that he has never known fear.

The fundamental qualities for good execution of a plan is first; intelligence; then discernment and judgment, which enable one to recognize the best method as to attain it; the singleness of purpose; and, lastly, what is most essential of all, will-stubborn will.
