The blessing of misfortune
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.
— Seneca, On The Shortness Of Life
