Every hour staunchly, as a Roman and a man, resolve to do the work in hand, with scrupulous and unaffected dignity, affectionately, freely, justly; securing respite for yourself from all other intruding regards. And this you will secure, if you perform each task as though it were your last, free from all waywardness, from passions that estrange from reason’s dictates, from insincerity, self-love, and discontent with destiny.

[Πάσης ὥρας φρόντιζε στιβαρῶς ὡς Ῥωμαῖος καὶ ἄρρην τὸ ἐν χερσὶ μετὰ τῆς ἀκριβοῦς καὶ ἀπλάστου σεμνότητος καὶ φιλοστοργίας καὶ ἐλευθερίας καὶ δικαιότητος πράσσειν καὶ σχολὴν σαυτῷ ἀπὸ πασῶν τῶν ἄλλων φαντασιῶν πορίζειν. ποριεῖς δέ, ἂν ὡς ἐσχάτην τοῦ βίου ἑκάστην πρᾶξιν ἐνεργῇς, ἀπηλλαγμένος πάσης εἰκαιότητος καὶ ἐμπαθοῦς ἀποστροφῆς ἀπὸ τοῦ αἱροῦντος λόγου καὶ ὑποκρίσεως καὶ φιλαυτίας καὶ δυσαρεστήσεως πρὸς τὰ συμμεμοιραμένα.]

Meditations [To Himself; Τὰ εἰς ἑαυτόν], Book 2, ch. 5 (2.5) [tr. Rendall (1898)]
    (Source)

(Source (Greek)). Other translations:

Let it be thy earnest and incessant care as a Roman and a man to perform whatsoever it is that thou art about, with true and unfeigned gravity, natural affection, freedom and justice: and as for all other cares, and imaginations, how thou mayest ease thy mind of them. Which thou shalt do; if thou shalt go about every action as thy last action, free from all vanity, all passionate and wilful aberration from reason, and from all hypocrisy, and self-love, and dislike of those things, which by the fates or appointment of God have happened unto thee.
[tr. Casaubon (1634), #2]

Take care always to pursue the Business in Hand with Vigour and Application; Remember your self a Man and a Roman; And let the Action be done with all the Dignity and Advantage of Circumstance: Let unaffected Gravity, Humanity, Freedom, and Justice shine through it. And be sure you entertain no Fancys, which may give check to these Qualities. This Task is very practicable if you will but suppose every thing you are upon your Last; If your Appetites and Passions don't cross upon your Reason; If you stand clear of Rashness, and don't complain of your Destiny, and have nothing of Insincerity, and Self-Love to infect you.
[tr. Collier (1701)]

Let this be your steadfast purpose to act continually, in all affairs, as becomes a Roman, and a man, with true unaffected dignity, kindness of heart, freedom, and justice; and disentangle your soul from other solicitudes. You shall thus disentangle yourself, if you perform each action as if it were your last: without temerity, or any passionate aversion to what reason approves; without hypocrisy or selfishness, or fretting at what providence appoints.
[tr. Hutcheson/Moor (1742)]

Take care always to perform strenuously the business in hand, as becomes a man and a Roman, with attention and unaffected gravity, with humanity, liberality, and justice; and call off your thoughts, for the time, from every other object. This you will do, if you perform every action as if it were the last of your life; if you act without levity or dissimulation, free from selfishness and from every passion inimical to right reason; and lastly from peevishness and dissatisfaction at those events, which are necessarily connected with our lot.
[tr. Graves (1792)]

Every moment think steadily as a Roman and a man to do what thou hast in hand with perfect and simple dignity, and feeling of affection, and freedom, and justice, and to give thyself relief from all other thoughts. And thou wilt give thyself relief if thou doest every act of thy life as if it were the last, laying aside all carelessness and passionate aversion from the commands of reason, and all hypocrisy, and self-love, and discontent with the portion which has been given to thee.
[tr. Long (1862)]

Take care always to remember that you are a man and a Roman; and let every action be done with perfect and unaffected gravity, humanity, freedom, and justice. And be sure you entertain no fancies, which may give check to these qualities. This is possible, if you will but perform every action as though it were your last; if your appetites and passions do not cross upon your reason; if you keep clear of rashness, and have nothing of insincerity and self-love to infect you, and do not complain of your destiny.
[tr. Collier/Zimmern (1887)]

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.
[tr. Hutcheson/Chrystal (1902)]

Every hour make up thy mind sturdily as a Roman and a man to do what thou hast in hand with scrupulous and unaffected dignity and love of thy kind and independence and justice; and to give thyself rest from all other impressions. And thou wilt give thyself this, if thou dost execute every act of thy life as though it were thy last, divesting thyself of all aimlessness and all passionate antipathy to the convictions of reason, and all hypocrisy and self-love and dissatisfaction with thy allotted share.
[tr. Haines (Loeb) (1916)]

Each hour be minded, valiantly as becomes a Roman and a man, to do what is to your hand, with precise ... and unaffected dignity, natural love, freedom and justice; and to give yourself repose from every other imagination. And so you will, if only you do each act as though it were your last, freed from every random aim, from wilful turning away from the directing Reason, from pretence, self-love and displeasure with what is allotted to you.
[tr. Farquharson (1944)]

Hour by hour resolve firmly, like a Roman and a man, to do what comes to hand with correct and natural dignity, and with humanity, independence, and justice. Allow your mind freedom from all other considerations. This you can do, if you will approach each action as though it were your last, dismissing the wayward thought, the emotional recoil from the commands of reason, the desire to create an impression, the admiration of self, the discontent with your lot.
[tr. Staniforth (1964)]

At every hour devote yourself in a resolute spirit, as suits a Roman and a man, to fulfilling the task in hand with scrupulous and unaffected dignity, and love for others, and independence and justice; and grant yourself a respite from all other preoccupations. And this you will achieve if you perform every action as though it were your last, freed from all lack of purpose and wilful deviation from the rule of reason, and from duplicity, self-seeking, and dissatisfaction with what is allotted to you.
[tr. Hard (1997 ed.)]

Concentrate every minute like a Roman -- like a man -- on doing what’s in front of you with precise and genuine seriousness, tenderly, willingly, with justice. And on freeing yourself from all other distractions. Yes, you can -- if you do everything as if it were the last thing you were doing in your life, and stop being aimless, stop letting your emotions override what your mind tells you, stop being hypocritical, self-centered, irritable.
[tr. Hays (2003)]

Every hour of the day give vigorous attention, as a Roman and 5 as a man, to the performance of the task in hand with precise analysis, with unaffected dignity, with human sympathy, with dispassionate justice — and to vacating your mind from all its other thoughts. And you will achieve this vacation if you perform each action as if it were the last of your life: freed, that is, from all lack of aim, from all passion-led deviation from the ordinance of reason, from pretence, from love of self, from dissatisfaction with what fate has dealt you.
[tr. Hammond (2006)]

Each and every hour make up your mind steadfastly as a Roman and as a man to accomplish the matter presently at hand with genuine solemnity, loving care, independence, and justice, and to provide yourself with relief from all other worries; and you will achieve this if you perform every action in your life as if it were your last, putting aside all aimlessness and emotional resistance to the choices of reason, and all pretense, selfishness, and discontent with what has been allotted to you.
[tr. Needleman/Piazza (2008)]

At every hour devote yourself in a resolute spirit, as befits a Roman and a man,* to fulfilling the task in hand with a scrupulous and unaffected dignity, and with love for others, and independence, and justice; and grant yourself a respite from all other preoccupations. And this you will achieve if you perform every action as though it were your last, freed from all lack of purpose and wilful deviation from the rule of reason, and free from duplicity, self-love, and dissatisfaction with what is allotted to you.
[tr. Hard (2011 ed.)]

At every hour, give your full concentration, as a Roman and a man, to carrying out the task in hand with a scrupulous and unaffected dignity and affectionate concern for others and freedom and justice, and give yourself space from all other concerns. You will give yourself this if you carry out each act as if it were the last of your life, freed from all randomness and passionate deviation from the rule of reason and from pretence and self-love and dissatisfaction with what has been allotted to you.
[tr. Gill (2013)]

Think steadily every moment about what you have to do, with a perfect and simple dignity, with feelings of affection, freedom and justice. Do not allow yourself to be distracted. Live every moment as if it were your last, thinking clearly, without passion. Do not allow yourself to be overcome by feelings of hypocrisy, narcissism or resentment.
[tr. McNeill (2019)]
