Context

“In such a matter we must not be always afraid of something being wasted or running over in our measure, or of more than is justly due being devoted to our friendship. But the last limit proposed is the worst, namely, that a friend's estimate of himself is to be the measure of our estimate of him. It often happens that a man has too humble an idea of himself, or takes too despairing a view of his chance of bettering his fortune. In such a case a friend ought not to take the view of him which he takes of himself. Rather he should do all he can to raise his drooping spirits, and lead him to more cheerful hopes and thoughts. We must then find some other limit.” source
