If one wants to succeed, then one should act as though one were genuinely confident about one' s abilities, even if one actually distrusts one' s skills. Success is much more easily obtained by those who genuinely believe themselves capable of succeeding than by those filled with self-doubts. Which one of the following statements, if true, most strengthens the argument? ['Success is usually more a matter of luck or determination than of skill.', 'Self-doubt can hamper as well as aid the development of the skills necessary for success.', 'Genuine confidence is often a by-product of pretended self-confidence.', 'Those who convince others that they are capable of succeeding usually have few self-doubts.']
