Look before you leap. Men of evil reputation, when they perform a good deed, fail to get credit for it. Might makes right. Misfortune tests the sincerity of friends. Misfortunes springing from ourselves are the hardest to bear.
Nature exceeds nurture.
Necessity is the mother of invention. Necessity knows no law. No arguments will give courage to the coward. No one can be a friend if you know not whether to trust or distrust him. No one truly forgets injuries in the presence of him who caused the injury.
