How we cite our quotes: (Line)
Quote #1
And yet don't look too good, nor talk too wise; (8)
The speaker introduces a theme that will be important later when the poem becomes more obviously political: balance. To be a good leader, the listener must not be "too" much of anything (too wise, too upright, etc.). Excess is no good.
Quote #2
If you can talk with crowds and keep your virtue,
Or walk with Kings---nor lose the common touch, (25-26)
The idea of talking with crowds makes us think of political speeches, while walking with kings suggests passing with social elites. A good leader must be able to get along with people from opposite ends of the social spectrum ("Kings" and "crowds").
