Sir Winston Churchill is a man to whom so many of life’s great quotes are attributed to and one of those is ” I like a man who grins when he fights“.
The best explanation I could find about the above mentioned famous quote was from WikiAnswers.
….When the great Winston Churchill said, “I like a man who grins when he fights,” he meant that such a man exudes and manifests courage by looking into the face of adversity and challenging it head on. He doesn’t run from fear, he engages it, and smiling during the contest is one way to not only embolden oneself but also to disarm and discourage the opponent, whether that opponent is an actual person or a condition. So . . . when you are up against an adversary, grin when you fight. It will help you overcome the adversity and triumph….
My reading of Churchill’s famous life quote is that it is better to face up to a problem in a confident manner and not to show negativity or fear. Putting on a brave face is in many ways halfway to winning the battle.
