A true vocation solidifies more easily when it does not have a favorable environment. When there are no incentives or, otherwise, when one loses out in exercising it, everything becomes much clearer, and a kind of strength springs from the realization that it is necessary to assume oneself and shameful to deny what one is. Those who carry on without a teacher, a friend, a social or professional environment to encourage them, without a push or even a favorable opinion, wake up one day and realize that they have developed a rock-solid will. And then they have to be very thankful for the circumstances that ultimately favored them.
