winners never quit.

Being conscientious and exercising mindfulness is what creates an environment for growth and hopefully wisdom. That is not to say that it should be taken to paralysis of analysis. A distorted thinking mind is just as limiting but a healthy, thinking person creates a bountiful harvest.

the best winner is who can know how to lose in life too ;)

If you're attached to the thinking (and feeling), you're losing. Let the war carry on. Just stand back and let it continue while you carry on living the life you've missed by trying to fight.
