Consider, that even in vain and frivolous actions, as at chess, tennis, and the like, this eager and ardent engaging with an impetuous desire, immediately throws the mind and members into indiscretion and disorder: a man astounds and hinders himself; he who carries himself more moderately, both towards gain and loss, has always his wits about him; the less peevish and passionate he is at play, he plays much more advantageously and surely.
