If you now neglect things and are lazy and are always making delay after delay and set one day after another as the day for paying attention to yours… - Epictetus

So decide now that you are worthy of living as a full-grown man who is making progress, and make everything that seems best be a law that you cannot go against. And if you meet with any hardship or anything pleasant or reputable or disreputable, then remember that the contest is now and the Olympic games are now and you cannot put things off any more and that your progress is made or destroyed by a single day and a single action

The chief task in life is simply this: to identify and separate matters so that I can say clearly to myself which are externals not under my control, and which have to do with the choices I actually control. Where then do I look for good and evil? Not to uncontrollable externals, but within myself to the choices that are my own...

If on the other hand, they identify their good and interests with things that are external and outside the sphere of will, they are bound to be impeded and frustrated, subservient to those who have authority over the things that you have admired and feared. They are also bound to be utterly irreverent since they think that God has a grudge against them, and to be unfair, since they always grab more for themselves; and they are bound to lack self-respect and generosity.

Are the Trojans wise or foolish? If they are wise, do not quarrel with them; if they are fools, ignore them.
