In the book Of Anger, Seneca draws on Fabius to teach a lesson from war that every citizen and leader and business person should be familiar with: “Fabius used to say that the basest excuse for a commanding officer is ‘I didn’t think it would happen,’ but I say it’s the basest for anyone. Thinking everything might happen; anticipate everything.” [..] We must keep our eyes open. We must consider all the potential consequences, even the unlikely or the unusual or the unintended ones. We must be ready. Fortune behaves as she pleases. So do our opponents. Don’t be surprised. There’s no excuse…except that you haven’t been doing your work.
