Quotation One

Failure is only postponed success as long as courage 'coaches' ambition. The habit of persistence is the habit of victory.
Herbert Kaufman

The meaning of the first quotation is that, it matters not how many time one fails in the path to victory. As long as the future victor still retains courage, which in turn would fuel his/her ambition, victory is undeniable. Persisting is the key to achieving what appears to be impossible. 

People that succeed always fail at that particular thing prior to their success. Courage cannot exist without fear, so fear of failure should not be an obstacle that prevents success. As long as the ambition is still present that the number of failures cannot stop victory. ..

This quote was likely recorded towards the end of the first World War, as this man was an American newspaperman and writer, and he lived from 1878 to 1947. So his quote probably reflects the allies victory during that war.
