ONE TRICK PONY SYNDROME

"People with great gifts are easy to find, but symmetrical and balanced ones never."

Ralph Waldo Emerson (1803-1882) U.S. poet/essayist/lecturer.

"Never" seems a little absolute, however the overriding sentiment is valid.

Being really good at one or two things does often come at the expense of much else of importance.

Strive for balance.
