I see this quote at KIPP everyday....

Cowardice asks the question - is it safe?
Expediency asks the question - is it politic?
Vanity asks the question - is it popular?
But conscience asks the question - is it right?
And there comes a time when one must take a position
that is neither safe, nor politic, nor popular;
but one must take it because it is right.
-Martin Luther King Jr.
