Courage in Torment

There are more things, Lucilius, likely to frighten us than there are to crush us; we suffer more often in imagination than in reality. Accordingly, some things torment us more than they ought; some torment us before they ought; and some torment us when they ought not to torment us at all. We are in the habit of exaggerating, or imagining, or anticipating, sorrow.
– Lucius Annaeus Seneca, Letters to Lucilius (Letter 13, verses 4 and 5)
