Keep a guard over your eyes and ears as the inlets of your heart, and over your lips as the outlet, lest they betray you in a moment of unwariness. Receive, coldly and dispassionately, every attention, till you have ascertained and duly considered the worth of the aspirant; and let your affections be consequent upon approbation alone. First study; then approve; then love.
