" It seems simple but, dear,
it means that integrity, loyalty, honor, and courtesy are the
safest and surest instruments for your success. In this selfish
world you will find many to tell you that a man cannot make his
way by sentiments, that too much respect for moral considerations
will hinder his advance. It is not so; you will see men
ill-trained, ill-taught, incapable of measuring the future, who are
rough to a child, rude to an old woman, unwilling to be irked by
some worthy old man on the ground that they can do nothing for
him; later, you will find the same men caught by the thorns which
they might have rendered pointless, and missing their triumph for
some trivial reason; whereas the man who is early trained to a
sense of duty does not meet the same obstacles; he may attain
success less rapidly, but when attained it is solid and does not
crumble like that of others. "

― Honoré de Balzac , Vadideki Zambak
