Of course it helps. Reading Marcus Aurelius' Meditations has a calming effect on me.
Even if I am unable to live up to Aurelius' standards I try to lean in that direction:
Hourly and earnestly strive, as a Roman and a man, to do what falls to your hand with perfect unaffected dignity, with kindliness, freedom and justice, and free your soul from every other imagination. This you will accomplish if you perform each action as if it were your last, without wilfulness, or any passionate aversion to what reason approves; without hypocrisy or selfishness, or discontent with the decrees of Providence.
2. Observe what grace and charm appear even in the accidents that accompany Nature’s work. Thus some parts of a loaf crack and burst in the baking; and this cracking, though in a manner contrary to the design of the baker, looks well and invites the appetite. Figs, too, gape when at their ripest, and in ripe olives the very approach to rotting adds a special beauty to the fruit. The droop of ears of corn, the bent brows of the lion, the foam at a boar’s mouth, and many other things, are far from comely in themselves, yet, since they accompany the works of Nature, they make part of her adornment, and rejoice the beholder. Thus, if a man be sensitive to such things, and have a more than common penetration into the constitution of the whole, scarce anything connected with Nature will fail to give him pleasure, as he comes to understand it. Such a man will contemplate in the real world the fierce jaws of wild beasts with no less delight than when sculptors or painters set forth for him their presentments. With like pleasure will his chaste eyes behold the maturity and grace of old age in man or woman, and the inviting charms of youth. Many such things will strike him, things not credible to the many, but which come to him alone who is truly familiar with the works of Nature and near to her own heart.
