Pursuing vengeance at all costs does not only cost you money, time, happiness,friends, good health, and peace, but it destroys you the avenger more than your target.
Remember, vengeance arises out of hate, and hate is like a poison. It endangers the person harbouring it that for whom it’s harboured.
The best revenge is insurmountable success. This will fill your enemies with jealous, hate, and poisonous vengeful feelings such that they choke themselves to destruction.
