Have been dipping into The Maxims of Washington. This is an exercise well worth the undertaking and should be done periodically. Having just come through the Thanksgiving holiday, this comment on the discontented struck me. The reverse of giving thanks.
.....Against the malignancy of the discontented, the turbulant, the vicious, no abilities; no exertions; nor the most unshaken integrity; are any safeguard....To John Jay, November 1, 1794
Yes, discontent is a cancer; and like the physical manifestation, it will destroy.
