Monday after work I went to my local barbershop for a haircut.  The owner, a bald-headed man in his sixties, motioned for me to sit in the center chair.  I was happy to have the owner cut my hair.  He's not the best barber in the shop but his haircuts are adequate and reliable.  He has four assistants: two young Hispanic guys, a middle-aged Hispanic guy, and an obese blonde woman.  The best barber, a true artist with a razor cut, is one of the young Hispanic guys.  Unfortunately, the worst barber is the other young Hispanic guy, and I can't keep track of which is which.  The middle-aged Hispanic guy does a good job but his scissors style is too jumpy for my peace of mind, and the blonde gives a mediocre haircut accompanied by non-stop chatter.  All in all, the owner is the safest bet. 
I had slogged through a long day at work and the cares of the world were weighing on me.  As I stared at the mirror on the wall, my reflection stared back with dull eyes.  I watched the owner buzz and clip my bushy hair into submission.  When the owner finished, I paid the bill and added a two dollar tip.  We parted on a cheerful note.
It was only later at the grocery store when I was flipping through a little book of daily quotations that I came to a disturbing realization.  Never once during my haircut did I think to look at the most interesting sight in the barbershop: the mounted head of a warthog on the back wall.  It is a fine warthog with a peaceful expression, the mark of a clear conscience.  It was a warthog that must have enjoyed a reputation for probity in his warthog community.  I had been so preoccupied and mind-deadened from work that I had forgotten to look at this excellent warthog.
Feeling uneasy, I consulted the chapter on contentment.  Several quotations spoke to my condition.
"Tension is who you think you should be. Relaxation is who you are." ~ Chinese Proverb
"What is important in life is life, and not the result of life." ~ Johann Wolfgang Von Goethe (1749 - 1832)
"One of the symptoms of an approaching nervous breakdown is the belief that one's work is terribly important." ~ Bertrand Russell (1872 - 1970)
To these, I add my own: "Take time to stop and enjoy the warthog."
