Let the degree of egotism be the measure of confidence.

Who makes quick use of the moment is a genius of prudence.

The man who loves with his whole heart truth will love still more he who suffers for truth.

He who, when called upon to speak a disagreeable truth, tells it boldly and has done is both bolder and milder than he who nibbles in a low voice and never ceases nibbling.

Be not the fourth friend of him who had three before and lost them.

Three days of uninterrupted company in a vehicle will make you better acquainted with another, than one hour's conversation with him every day for three years.

The jealous are possessed by a mad devil and a dull spirit at the same time.
