They that are sinful never seek so much to ascertain the good qualities of others as to ascertain their faults. He that desires the highest success in all matters connected with worldly profit, should from the very beginning practise virtue, for true profit is never separated from heaven.

In plain words: Bad people look for faults in others more than for their good qualities. If you want real success in worldly matters, practise goodness from the start. True gain is never separate from what is right.
