The man who is honest and good ought to be exactly like a man who smells strong, so that the bystander as soon as he comes near him must smell whether he choose or not. — Meditations, Book XI

My Take – Your reputation will precede you.  If you are an upstanding person, others will know that by the way you deal with them and others.  A talent need not be advertised, because it will make itself evident in the most effective way:  you will exercise it and others will notice. There is no need to toot your own horn, nor is it necessary that others sing your praises.
