Keep some virtues private. Seneca, Epistulae 1.5.1-3

Like others (notably Jesus in the Sermon on the Mount), Seneca offers a lesson that can seem counter-intuitive to many today. Keep some good things private. Don't tell others everything about yourself, especially not the best parts (in your estimation). If you want to keep virtue intact, you need to know that it is something you do for its own sake, not so that others may see (and praise, or be disgusted, like those who avoided philosophy in Seneca's time because its loudest public advocates tended to be obnoxious Cynics trying to outdo Diogenes of Sinope). You can hear this passage <here>.

Quod pertinaciter studes et omnibus omissis hoc unum agis, ut te meliorem cotidie facias, et probo et gaudeo, nec tantum hortor ut perseveres sed etiam rogo. Illud autem te admoneo, ne eorum more qui non proficere sed conspici cupiunt facias aliqua quae in habitu tuo aut genere vitae notabilia sint; asperum cultum et intonsum caput et neglegentiorem barbam et indictum argento odium et cubile humi positum et quidquid aliud ambitionem perversa via sequitur evita. Satis ipsum nomen philosophiae, etiam si modeste tractetur, invidiosum est: quid si nos hominum consuetudini coeperimus excerpere? Intus omnia dissimilia sint, frons populo nostra conveniat. Non splendeat toga, ne sordeat quidem; non habeamus argentum in quod solidi auri caelatura descenderit, sed non putemus frugalitatis indicium auro argentoque caruisse. Id agamus ut meliorem vitam sequamur quam vulgus, non ut contrariam: alioquin quos emendari volumus fugamus a nobis et avertimus; illud quoque efficimus, ut nihil imitari velint nostri, dum timent ne imitanda sint omnia.

I approve your steadfast dedication to study, rejoicing that you are willing to give up all things to do only that which will make you a better person each day. I exhort and even plead with you to continue this course. But still I must warn you against the character of those who desire not to advance but to be seen, lest you find yourself altering your appearance or manner of life to attract attention. Rough manners, hair untrimmed, beard gone wild, loud hatred for money, bed laid on the ground: these, and any other perverse methods for courting the public, you should avoid. Calling ourselves philosophers is bad enough, even if we manage it discreetly: what if we should start to exempt ourselves from the society of other folk? That which makes us unique should be kept hidden safely inside our private life, while our public presentation shows the people what they recognize. Your toga should not shine, but neither should it be falling to pieces. We should not have enough money to make a statue of solid gold, but neither should we deem it a mark of frugality to lack gold and silver. Our philosophy should be something we do in order to pursue a life better than the common one, not contrary to it. Otherwise, we drive away those whom we wish to help, and ward them off, making them desire to imitate no habit of ours, while they are still in thrall to the fear that they must imitate all of them.
