We lose or win a battle in our minds before fighting.
It is more about our way of seeing and observing the scenario and acting on it.
If we are not optimistic and confident, how are we going in the trenches with high morale and willingness to sacrifice for the cause?
People dying of regrets or losing a battle without putting up a fight suffer beyond the battlefield. Their loss gets innate to their everyday life and behavior.
Some people put up a fight or die trying.
Many others live another day without doing anything and dying within.
