If you are bent on assuming a pose and never reveal yourself to anyone frankly, in the fashion of many who live a false life that is all made up for show; for it is torturous to be constantly watching oneself and be fearful of being caught out of our usual role. And we are never free from concern if we think that every time anyone looks at us he is always taking-our measure; for many things happen that strip off our pretence against our will, and, though all this attention to self is successful, yet the life of those who live under a mask cannot be happy and without anxiety.
Seneca the YoungerWe should every night call ourselves to an account: What infirmity have I mastered today? What passions opposed? What temptation resisted? What virtue acquired? Our vices will abate of themselves if they be brought every day to the shrift.
Seneca the YoungerThe condition of all who are preoccupied is wretched, but most wretched is the condition of those who labor at preoccupations that are not even their own, who regulate their sleep by that of another, their walk by the pace of another, who are under orders in case of the freest things in the world-loving and hating. If these wish to know how short their life is, let them reflect how small a part of it is their own.
