I very much like the following maxim of Cicero’s:
Nevertheless, no theater for virtue is greater than one’s conscience. 
What he meant by this was that one’s own conscience should guide the performance of good works. He was expressing his disapproval of those who did things for the purpose of gaining public favor, instead of following that inner voice which represents man’s instinctive sense of justice. What should be paramount in one’s mind are not specious public displays, or a craving for shameless notoriety; what should be controlling are the dictates of one’s own conscience.
