Put up with being perceived as ignorant

Epictetus, Enchiridion, Chapter 13:

If you want to make progress, put up with being perceived as ignorant or naive in worldly matters, don't aspire to a reputation for sagacity. If you do impress others as somebody, don't altogether believe it. You have to realize, it isn't easy to keep your will in agreement with nature, as well as externals. Caring about the one inevitably means you are going to shortchange the other.

Compare with Gracian, who would suggest we hide the depth of our knowledge, but for strategic reasons, and in order to increase our ability to manipulate and surprise others.
