Status Anxiety by Alain De Botton (2004)

The need to beware of colleagues:
‘Men are so false, so insidious, so deceitful and cunning in their wiles, so avid in their own interest, and so oblivious to others’ interests, that you cannot go wrong if you believe little and trust less.’ –GUICCIARDINI

The need to lie and exaggerate:
‘If you are involved in important affairs, you must always hide failures and exaggerate successes. It is swindling but since your fate more often depends upon the opinion of others rather than on facts, it is a good idea to create the impression that things are going well.’ –GUICCIARDINI

The need to threaten:
‘It is much safer to be feared than loved. Love is sustained by a bond of gratitude which, because men are excessively self-interested, is broken whenever they see a chance to benefit themselves. But fear is sustained by a dread of punishment that is always effective.’ –MACHIAVELLI
