Seneca
– I realized that your grief should not be intruded upon while it was fresh and agonizing, in case the consolations themselves should rouse and inflame it: for an illness too nothing is more harmful than premature treatment. So I was waiting until your grief of itself should lose its force and, being softened by time to endure remedies, it would allow itself to be touched and handled.[Now] I shall offer to the mind all its sorrows, all its mourning garments: this will not be a gentle prescription for healing, but cautery and the knife.

In consonance with his strategy for inoculating oneself against misfortune, Seneca considers the benefits of such a raw confrontation of sorrow:
Let those people go on weeping and wailing whose self-indulgent minds have been weakened by long prosperity, let them collapse at the threat of the most trivial injuries; but let those who have spent all their years suffering disasters endure the worst afflictions with a brave and resolute staunchness.
Everlasting misfortune does have one blessing, that it ends up by toughening those whom it constantly afflicts.
Let those people go on weeping and wailing whose self-indulgent minds have been weakened by long prosperity, let them collapse at the threat of the most trivial injuries; but let those who have spent all their years suffering disasters endure the worst afflictions with a brave and resolute staunchness.
