Life without Disturbance, Soldiers of Fate

But those occupied with the prognostication of the future and the truth, by gaining a soul free and not enslaved, think slightly of fortune, and do not obstinately persist in hope, and do not fear death, but spend their lives without disturbance by training the soul ahead of time to be confident, and neither rejoice excessively in the case of good nor are depressed in the case of foul, and are content with what is present. And those who are not in love with the impossible carry along that which ordained, and being estranged from all pleasure or flattery, they are established as soldiers of fate.
