The flatterer's object is to please in everything he does; whereas the true friend always does what is right, and so often gives pleasure, often pain, not wishing the latter, but not shunning it either, if he deems it best. Plutarch
To make no mistakes is not in the power of man; but from their errors and mistakes the wise and good learn wisdom for the future. See image Plutarch
I don't need a friend who changes when I change and who nods when I nod; my shadow does that much better. See image Plutarch
