If you are putting together Buffett's Twain influences, include
his lyrics from "Take Another Road":

Also see Buffett's book _Tales from Margaritaville_.
Shelley Fisher Fishkin's book _Lighting Out for the Territory_
documents a letter from Buffett to Gretchen Sharlow in August 1995
wherein Buffett acknowledged Twain as an important influence in his
works.
If Buffett is not a member of the Mark Twain Luncheon Club,
he ought to be.
As to _Readers' Digest_ -- they missed a great opportunity to
put together a Buffett/Twain quote comparison article.
