I have always loved this quote from legendary raconteur and racketeer Walter E. Scott, but had forgotten it until reminded of it on Twitter this morning. By the way, my late grandfather Dr. J. Vernon McGee met this man who was also known as "Death Valley Scotty" at Scotty's Castle back in the middle part of the 20th century.
"...Don’t give advice---nobody will take it anyway. Don’t complain. Don’t explain.”
