If thou wouldst make progress, be content to seem foolish and void of understanding with respect to outward things. Care not to be thought to know anything. If any should make account of thee, distrust thyself.

— Epictetus

When you have decided that a thing ought to be done, and are doing it, never shun being seen doing it, even though the multitude should be likely to judge the matter amiss.

— Epictetus
