“If you have accomplished all that you have planned for yourself, you have not planned enough.”
In Quote, Unquote (1977) by Lloyd Cory, p. 6, this statement was simply attributed to the Meggido Message which is the name of a publication by the Meggido Church http://www.megiddo.com/, but immediately following a quote by Hale. This may have led to it being attributed to Hale in The Quotable Manager : Inspiration for Business and Life (2006) by Joel J. Weiss, p. 128; a similar expression "If you have achieved all you have planned for yourself, you have not planned enough" occurs in two works by John Mason: Let Go of Whatever Makes You Stop (1994), p. 79, and Know Your Limits — Then Ignore Them (2000), p. 123
