Now is the time and here is the place. There is no need to seek solace in faraway places and idyllic spots. Your best retreat lies within and you will return from it refreshed and ready to resume your duties:
Men seek retreats for themselves, houses in the country, sea-shores, and mountains; and you too are wont to desire such things very much. But this is altogether a mark of the most common sort of men, for it is in your power whenever you choose to retire into yourself. Nowhere does a man find more quiet or more freedom from trouble than in his own soul, particularly when, by looking into his own inner thoughts, he is immediately in perfect tranquility. And I affirm that tranquility is nothing else than the good ordering of the mind. Constantly then give to yourself this retreat, and renew yourself; and let your principles be brief and fundamental. Then as soon as you recur to them, they will be sufficient to cleanse the soul completely, and to send you back free from all discontent with the things you return to.
