Quit your bitchin'

Any cranky old  fool can criticize, condemn and complain - and most fools do. Benjamin Franklin

The shorten modified version comes from Dale Carnegie. A misplaced and long ago forgotten longer version, part of a self-improvement plan Franklin drew up as a young man in 1726, goes:

 ...I resolve to speak ill of no man whatever, not even in a matter of truth; but rather by some means excuse the faults I hear charged upon others, and upon proper occasions speak all the good I know of every body.

While we are on the topic of fools, let's quote Buck Owens:

There's no fool like an old fool 
That's loved and lost at least a hundred times 
There's no fool like an old fool 
That keeps on falling for the same old line.

his and hers?

Fools come in all sizes, shapes, and ages, mostly recognizable to everyone but the fool. The old man has lots of things to bitch about, still he keeps them to himself.

As Lou Holtz said, “Never tell your problems to anyone...20% don't care and the other 80% are glad you have them.”
